Type 89 Knee Mortar at James D Julia

Screen Shot 2015-09-15 at 1.16.29 PM

The Type 89 grenade discharger, commonly known as the “knee mortar” was a Japanese light infantry weapon introduced in 1929 which blurs the lines between grenade launcher and mortar. Like a mortar, it fires propelled explosive bombs in a high-angle indirect fire role, but it has a rifled barrel and uses a range adjustment […]

RIA: Hotchkiss Revolving Cannon Reproduction

Screen Shot 2015-08-17 at 7.37.50 AM

The Hotchkiss Revolving Cannon was developed in the 1870s as a competitor to the other manually-operated machine guns of the era, guns like the Gatling, Gardner, and Nordenfelt to name a few. What made the Hotchkiss stand out is that while the other guns were mostly built in rifle calibers, with larger options available, the […]

T124E2 76mm Anti-Tank Gun

The T124E2 was the last US antitank gun, and was discontinued after only about 100 had been made – before it was put into service. It was a high velocity 76mm piece, and was replaced by the much smaller 75mm recoilless rifle.

US M3 37mm Antitank Gun (Video)

The M3 was the first real anti-tank gun adopted by the US military, and it was not formally adopted until 1940 – and was thoroughly obsolete in Europe by 1942. The initial design was based on a pair of German PAK-36 guns, but in its production guise the M3 was a much simpler gun. It […]

Bethlehem Steel 37mm Cannon – Looking for Data

I recently got an email from a young man named Paul who is working on restoring a Bethlehem Steel 37mm cannon as an Eagle Scout project. The gun is sitting outside an American Legion post, where I expect it has been for many, many decades. It appears to be mostly complete with the major exception […]

Vintage Saturday: Fire Support

US troops demonstrating use of an M1916 37mm gun

Everyone stare straight ahead and look serious!

One of the photos that didn’t make the cut for the 2015 Forgotten Weapons Calendar: US troops demonstrating use of an M1916 37mm gun. Note how the ammo is supplied on a cloth belt – it was made for use in 37mm Vickers Pompoms.


Krupp 50mm Mountain Gun (Thai Model 1902)

We’re taking a look at another artillery piece today, a 50mm mountain gun made for Siam (now Thailand) by the German Krupp company. It is a relatively simple (and thus relatively inexpensive at the time) design, with no recoil mechanism or adjustable traverse:

Vintage Saturday: Shaped Charge


I got two warheads, one for each of ya’!

This contraption is a Hungarian M1944 (1944 Mintá = 44M) double AT Projector (dupla páncéltörövetö) aka the Buzogányvető (= the Mace). Only 700 units were made, and they served as HE/AT weapona. The warheads each hold 4.21 kg (9.27 lb) of high explosive, and […]

Russian RG-6 Grenade Launcher and German Repair Depot Footage

RG-6 40mm grenade launcher

Something new and something old today…

RG-6 40mm grenade launcher

From long-time contributor Hrachya, we have a Russian manual for the RG-6 grenade launcher. This is a pretty recent design, having gone into production in the 1990s. It fires the same 40mm caseless grenades used by the older GP-25 underbarrel unit found mounted on […]

37mm Gun, Bethlehem, Semi-Automatic (Video)

The 37mm gun was found in many guises during World War One – that caliber was the smallest allowed to use exploding projectiles by the 1899 Hague accords. Every nation in the world, it seems, used 37mm guns of one type or another. Well, one particular version I had the chance to look at was […]
