Published Apr 16, 2024The ABC of Hand Tools (1945) is a Walt Disney Co. produced training and educational film for General Motors (GM) about proper use of hand tools. The film, which is in Technicolor, is fully animated and opens with a caveman character “Primitive Pete” seen inventing the first hand tool: an early model hammer made from stone with a stick handle. The film then goes on to elegantly show different types of basic hand tools such as the hammer, screwdriver, wrench, and pliers and show their proper uses, design elements and proper care.

M14: America’s Worst Service Rifle – What Went Wrong?
Forgotten Weapons
Published Apr 15, 2024While the US never adopted a significant variation of the M1 Garand (excluding sniper models), testing continued on new iterations and features throughout the war. By the time the war ended, the US military had some specific ideas about what it wanted in a new service rifle. That being, something lighter, capable of automatic fire, and to have one single platform replace the M1 Carbine, M3A1 Grease Gun, M1 Garand, and M1918A2 BAR. New rifles to meet these requirements were developed by Springfield, Remington, and Winchester, ultimately competing against the FN FAL for US service use. The Springfield T44E4 won out (barely) and was adopted on May 1, 1957 as the M14 rifle.
Production of the M14 was plagued by problems, largely due to quality control lapses. Early in production there were heat treatment problems that led to sheared looking lugs and broken receivers. Once those were addressed, the main problem became one of accuracy, with a shocking number of M14s failing to meet the 5.6 MOA minimum accuracy standard. Ultimately production ended in 1963 with 1.38 million M14s produced, and the M16 took over as the new American service rifle.

Chieftain V T-62 | Operation Nasr, Iran – Iraq War, 1981
The Tank Museum
Published Apr 13, 2024Two tanks designed to fight each other in Northern Europe would face each other during the Iran-Iraq war in 1981. On one side, the British built Chieftain MBT. On the other, the Soviet-built T-62.

Electrolux Charlton: Washing Machine Company Converts Bolt Action to Semiauto
Forgotten Weapons
Published Mar 25, 2024The Charlton was a conversion of a bolt action Lee rifle into a light machine gun, designed by New Zealander Phillip Charlton. Some 1500 were made in New Zealand, but a bit later it appears that there was an effort to also produce the gun in Australia. The Electrolux company (the same one that makes washing machines and other home appliances today) made a few prototypes.
The Electrolux version is different from the original in a couple ways. While the basic conversion mechanism is the same, the Electrolux is more refined, with a shorter gas system and a fairly clean action cover over the working parts. It is also semiautomatic only, intended to be a shoulder-fired rifle where the original was made for the LMG role. Electrolux also used standard No1 MkIII rifles as its base, where the originals were made from a variety of mostly worn out Lee Metfords and Long Lees.
The Electrolux contract was cancelled in June 1944, and only a few prototypes were made. This example is in the British Royal Armouries collection, to whom I am grateful for the access and the trust to take it apart for you!

How the First Tanks CONQUERED the Trenches
The Tank Museum
Published Mar 16, 2024This is the story of the evolution of the tank during World War One. Notorious for its appalling human cost, the First World War was fought using the latest technology – and the tank was invented to overcome the brutally unique conditions of this conflict.
Arriving at the mid-point of the war, they would be built and used by the British Commonwealth, French and German armies – with the US Army using both British and French designs.

Bigger Isn’t Always Better: A1E1 Independent | Tank Chats Reloaded
The Tank Museum
Published Mar 1, 2024A bigger tank is a better tank, right? Wrong.
Meet the Interwar Vickers A1E1 Independent: a failed prototype, a prototype that proved bigger isn’t always better. Impractical and expensive, it was never accepted into service – but it is said to have inspired equally cumbersome designs including the German Neubaufahrzeug and the Soviet T-35.
Join David Willey, The Tank Museum Curator, as he examines one of the more unusual vehicles in the collection – and discover how it became a focus for political espionage in the early 1930’s.

The Manda: Croatia’s Minimalist .50 BMG
Forgotten Weapons
Published Feb 21, 2024The Manda is a rifle that was designed for the Croatian Special Police at the beginning of the Homeland War in 1991. At that point, the Special Police (basically the SWAT teams) were basically the only really well-trained fighters in the country with combat experience. They wanted .50 BMG anti-material rifles for the war that was breaking out, and the Croatian Ministry of the Interior developed and produced the Manda for them.
Specifically, the rifle was designed by engineer Petar Vucetic (and named after his sister). Mechanically, it is a very simple rifle, with two large locking lugs, a tubular stock, M70 AK pistol grip, and a barrel made from a turned-down Browning M2 bolt with a large muzzle brake. A total of 84 were made, fitted with Leupold scopes and mounts with integrated BDC cams for use from 300 out to 1000 meters.

Evolution of The Churchill Tank | “No Damn Good”?
The Tank Museum
Published Feb 17, 2024Designed by a company that had never built a tank before with the Prime Minister, Winston Churchill, looking over their shoulders and plagued by mechanical teething troubles, the Churchill tank had unpromising beginnings. Despite this, it became one of the most successful British tanks of WW II: heavily armoured, not fast but with superb climbing ability, the Churchill served not only as a gun tank but the basis many of the specialised vehicles that helped the British and Canadian Armies ashore on D-Day.

Grant Hammond .32 ACP Prototype
Forgotten Weapons
Published Apr 6, 2015Grant Hammond is best known (to the extent he is known at all) for a .45 caliber pistol submitted to US military trials in 1917 and 1918. This pistol is a proof of concept prototype embodying some of the concepts that would go into the later .45 caliber pistol, and also showing some concepts that would not see further use. This .32 ACP prototype features a hybrid blow forward / blow back mechanism in which the slide uses a gas trapping system to move forward and the bolt moves backward. It also has a unique system for automatically ejecting the magazine when empty. Truly one of the most mechanically unusual pistols I have ever seen.

Patchett Machine Carbine Mk I: Sten Becomes Sterling
Forgotten Weapons
Published Feb 14, 2024The Patchett Machine Carbine Mk I is the predecessor to the Sterling SMG. It was developed by George William Patchett, who was an employee of the Sterling company. At the beginning of the wear, Sterling was making Lanchester SMGs, and Patchett began in 1942 working on a new design that was intended to be simpler, cheaper, and lighter than the Lanchester. He used the receiver tube dimensions from the Sten and the magazine well and barrel shroud from the Lanchester. His first prototypes were ready in 1943, but it wasn’t until early 1944 that the British government actually issued a requirement for a new submachine gun to replace the Stens in service.
The initial Patchett guns worked very well in early 1944 testing, which continued into 1945. It ultimately came out the winner of the trials, but they didn’t conclude until World War Two was over — and nothing was adopted because of the much-reduced need for small arms. Patchett continued to work on the gun, and by 1953 he was able to win adoption of it in the later Sterling form — which is a story for a separate video.
The Patchett was not used in any significant quantity in World War Two. At most, a few of them may have been taken on the parachute drops on Arnhem — there are specifically three trials guns which appear referenced in British documents before Arnhem, but are never mentioned afterwards (numbers 67, 70, and 72). Were they taken into the field? We really don’t know.

Battle Rifles of World War Two: Overview
Forgotten Weapons
Published Jan 26, 2024Today we are going to take a look at the three main battle rifles of World War Two — the M1 Garand, the SVT-40, and the Gewehr 43. We will also consider the SVT-38, Gewehr 41(W), and Gewehr 41(M). The United States, Soviet Union, and Germany were the three countries that fielded large numbers of semiautomatic full-power rifles in combat in WW2; how did they differ in their approaches to infantry firepower?
