Last Gasp of the German Maxim: the Air-Cooled MG 08/18
Forgotten Weapons
Published 7 Jun 2023The MG 08/18 was developed at the very end of World War One as a lighter alternative to the MG 08/15. It used an air-cooled barrel, and between not needing water and having lighter parts it managed to weigh about 6 pounds less than the 08/15. Only a few hundred appear to have been produced before the end of the war, and they were not used by the German military during the Weimar era (the Mg 08/15 was). The 08/18 barrel jacket served as the basis for the MG34 barrel shroud, interestingly.
Thanks to Limex for giving me access to this very rare gun to film for you!

The William Tell Aerial Gunnery Competitions; The CF-101 Voodoo in action
Polyus
Published 23 Aug 2021William Tell: an aerial gunnery competition to assess NORAD’s interceptor squadrons. Canadian CF-101s entered 7 of these competitions and won 3 overall “Top Gun” awards as well as one “Top Unit” award. Pretty impressive results when considering how few squadrons Canada fielded as compared with the vast United States Air Force. Results confirmed that the CF-101s on quick reaction alert at bases across the country were indeed useful in their defense.

MGD PM9 Rotary-Action Submachine Gun
Forgotten Weapons
Published 23 May 2017The PM9 was an interesting an unique submachine gun designed by Louis Debuit for the French firm Merlin and Gerin (hence the MGD name – Merlin, Gerin, Debuit) in the late 1940s and early 50s. The design was intended to provide a very compact package, which it did with a very short action, folding stock, and folding magazine.
The PM9 uses a delayed blowback action, and the delaying is done by a rotating flywheel-type block and clock spring. The bolt and flywheel act somewhat like the piston and crank in an engine. As the bolt (piston) moved rearward in a straight line, it forces the flywheel (crank) to rotate because the two are connected. In the case of the PM9, the connection is a nub on the flywheel that rides in a vertical slot in the bolt. The flywheel is pushing against the clock spring to rotate, and the combination of the its inertia and spring pressure keep the bolt closed long enough for pressure to drop to a safe level. The rotary action allows this to be done in a much smaller package than typical submachine guns.
The PM9 was initially chambered for 7.65 French Long, but quickly changed to standard 9mm Parabellum for the production models. It used the same magazine as the German MP38/MP40, giving it a 32-round capacity. In addition to the model with a skeletonized folding stock, the PM9 was also available with a fixed wooden stock and either short barrel of long carbine barrel. A relatively small number of guns were produced in France in 1954 and 1955, but they failed to find commercial success. In 1956 the German Erma company acquired a license to build the PM9, but abandoned the idea after making a few prototypes.

Gaulois Palm Pistol
Forgotten Weapons
Published 23 Nov 2014The Gaulois (Gallic) was a compact squeeze-type palm pistol made by the Manufrance concern in St. Etienne in the 1890s. It held 5 rounds of 8mm ammunition (similar to the .32 Extra-Short used in other types of palm pistols) and was fired by squeezing the rear grip into the body of the gun.
As with the other weapons of this type that achieved some popularity in the 1880s through early 1900s, the Gaulois eventually faded from the market because of the improvements in conventional handguns. Something like a compact Iver Johnson revolver offered all the capabilities (if not more) of a Chicago Protector or My Friend or Gaulois, without the loading and aiming difficulties of those designs.

Girardoni Air Gun (original 1780 example)
Forgotten Weapons
Published 7 Jun 2014The Girardoni (also spelled Girandoni) air rifle was a very advanced design adopted in 1780 by the Austrian Army. While the standard arm of the day was a single-shot flintlock, the Girardoni offered a massive firepower advantage to the men who carried it. The guns (designed by Bartholomäus Girardoni, of Vienna) had a magazine capacity of 22 round balls, which could all be fired within 60 seconds. The balls were .46 caliber, weighing approximately 153 grains, and were propelled at 400-450 feet per second. They were rumored to be silent, but actually had a loud report (although quieter than gunpowder firearms). One of these rifles was carried by the Lewis & Clark expedition into the American West.
The Austrian Army used them for a relatively short time — they were taken out of service by Imperial order in 1788, and issued back to Tyrolian sniper units only in 1792. The reasons for their replacement were more logistical than the result of any actual shortcoming with Girardoni’s design. The problem was that they required special training to use (compared to a normal firearm), required specially trained and equipped gunsmiths to repair and maintain, and difficulty maintaining them in combat conditions. Dr. Robert Beeman has written an outstanding illustrated article on Austrian airguns in general and the Girardoni in particular, which I highly recommend for anyone interested in more detail on these fascinating weapons:

However, I am privileged to be able to share with you this video of an original 1780 Girardoni put together by Luke Haag for presentation at the 2014 AFTE conference in Seattle. Mr. Haag does a great job explaining the operation of the gun, its capabilities and accessories.

MAS 49: A Universal Service Rifle
Forgotten Weapons
Published 20 May 2019As the MAS 44 saw combat service with French Marines in Indochina, some of its shortcomings began to reveal themselves. The rifle was reliable and durable, but it lacked some capabilities, most importantly rifle grenade launching and an optics mounting. After a test series of MAS 44A rifles, a new pattern was adopted as the MAS 49 and put into production in 1951.
A total of about 80,000 MAS 49 rifles were made, and they incorporated a scope mounting dovetail in the left side of the receiver and a grenade launching muzzle device and sight. In addition, the bayonet was left out, as it was no longer seen as necessary. Not all rifles were used with scopes or for launching grenades, but with the universal capability it was simple to adapt any rifle to whatever specialized role was required. Ultimately the MAS 49 would be replaced again in only a few year, by the MAS 49-56 iterative improvement — but that’s a subject for a future video.

A new paper on the cancellation of the Avro Arrow in 1959
The National Post republished a Canadian Press article about a new research paper by Alan Barnes in the Canadian Military History journal:
In the years after the Second World War, Canada developed its ability to prepare strategic intelligence assessments on defence and foreign policy, the paper notes. It would no longer have to rely entirely on assessments from the United States and Britain.
The analytic capability allowed Canada to fully participate in preparing the assessments on the Soviet threat to North America that would underpin joint Canada-U.S. planning for continental defence, Barnes notes.
“The CF-100 Canuck, a jet interceptor developed and manufactured in Canada, was just entering service, but there were already concerns that it might soon be outclassed by newer Soviet bombers operating at higher altitudes and faster speeds.”
In November 1952, the Royal Canadian Air Force called for an aircraft with a speed of Mach 2 and the ability to fly at 50,000 feet. “These demanding specifications contributed to the escalating costs and frequent delays in the CF-105 program.”
The Soviets would soon display a new long-range jet bomber, the Bison, at the 1954 May Day parade in Moscow. At an airshow the following year, a fly-past of 28 Bison seemed to indicate that the bomber had entered serial production, two years earlier than predicted, the paper says. In fact, only 18 prototype aircraft participated in the airshow, flying past several times to give the impression of larger numbers.
Even so, this display, along with the appearance of a new Soviet long-range turboprop bomber, the Tu-95 (dubbed the Bear), raised fears that the Soviet Union would soon outnumber the United States in intercontinental bombers, sparking a “Bomber Gap” controversy that figured prominently in American politics, the paper says.
[…]
A January 1958 assessment, “The Threat to North America, 1958-1967”, by Canada’s Joint Intelligence Committee, a co-ordinating body, ultimately had the greatest impact on decisions related to the Arrow, the paper says.
The assessment laid out clear judgments concerning the imminent transition from crewed bombers to ballistic missiles and described the limited size and capabilities of the Soviet bomber force, Barnes notes.
It observed that the Soviet ballistic missiles which were on the verge of being developed were likely to be markedly superior to the foreseeable defences, and concluded that missiles would progressively replace aircraft as the main threat to North America.
The assessment said this meant there would be little justification for the Soviet Union to increase the number of bombers, or to introduce new ones, after 1960.
“The (Joint Intelligence Committee)’s January 1958 assessment was correct in foreseeing Moscow’s shift from bombers to missiles over the subsequent decade,” Barnes writes.
He points out that following the Sputnik launch, Soviet leader Nikita Khrushchev came to see missiles as a panacea for a range of defence problems and as a cheaper alternative to conventional weapons. “With the Soviet bomber force now looking irrelevant and obsolete, it was relegated to a secondary position in Soviet military thinking.”

Wire Guided Tank Killer | Swingfire | Anti-Tank Chats
The Tank Museum
Published 2 Jun 2023In this video, Chris Copson looks at the Swingfire, a Cold War period anti-tank guided weapons system. This powerful and hard-hitting missile was mounted on vehicles including Striker, Ferret, and FV 432. With a range of up to 4km, it had the significant advantage that it would outrange tank guns and could be fired remotely by the controller, enabling the launch vehicle to remain in cover.

QotD: Logical consistency isn’t their jam
The same people who last week were screeching about the government having concentration camps now want me to give my AR15s to that same government.
The same people who last month were hyperventilating about the government slaughtering black people now expect me to surrender my guns to that same government.
The same people who last year were setting stuff on fire and yipping about the government rounding up the gays and Muslims for liquidation now think it’s a good idea for me to just hand over my rifles to that same government.
You chuckleheads need to make up your damned minds.

BM59: The Italian M14
Forgotten Weapons
Published 25 Oct 2017After World War Two, both the Beretta and Breda companies in Italy began manufacturing M1 Garand rifles. When Italy decided that they wanted a more modern selective-fire, magazine-fed rifle, they chose to adapt the M1 Garand to that end rather than develop a brand new rifle. Two Beretta engineers, Vittorio Valle and Domenico Salza, began work in 1957 on what would become the BM-59. Prototypes were ready in 1959, trials were run in 1960, and by 1962 the new weapon was in Italian military hands.
The BM59 is basically an M1 Garand action and fire control system, but modernized. The caliber was changed to 7.62mm NATO, and the barrel shortened to 19.3 inches. A simple but effective selective fire system was added to the fire control mechanism, and the en bloc clips replaced with a 20-round box magazine (and stripper clip loading guide to match). A folding integral bipod was added to allow the rifle to be used for supporting fire on full auto, and a long muzzle device was added along with a gas cutoff and grenade launching sight to allow the use of NATO standard 22mm rifle grenades.
In this form, the BM59 was a relative quickly developed and quite successful and well-liked rifle. In addition to the Italian military, it was purchased by Argentina, Algeria, Nigeria, and Indonesia. A semiautomatic version was made for the US commercial market and designated the BM62, and a small number of fully automatic BM-59 rifles — like the one in this video — were imported into the US before the 1968 Gun Control Act cut off importation of foreign machine guns.

Brun-Latrige Model 1900
Forgotten Weapons
Published 14 Apr 2016Patented in 1896, this is one of several models of unique pocket pistols designed by Paul Brun-Latrige. He was a manager of the Manufrance company located in St. Etienne France, a large mail-order catalog company that produced a wide variety of products. Early versions of this pistol used a ring trigger mechanism and a 5mm cartridge, while this one uses a folding trigger and is chambered for an 8mm round (the same ammunition used in Manufrance’s Gaulois palm pistols, I suspect).
