The stubby little French canon de 75 mm Blockhaus Schneider was the main gun of the Schneider CA1, France's first tank to see combat, and was used in the Renault FT 75 BS in the aftermath of WWI. The little Renault was arguably world's first self-propelled gun (tracked, armored artillery piece) in the modern sense. It also appears to have been used in pintle mounts in the field and, one would assume from the name, in fortifications.

Two requests...

1) Does anyone have any detailed specs (dimensions, weight, ammunition types, ballistics, performance) for the 75mm Blockhaus Schneider?

2) Were there any other applications for this funny little gun in vehicles or otherwise?

Cheers,

Matthew

It may help your search if you use it French army designation: Canon de 75 court modèle 1916 Schneider

From the Schneider CA1 Wikipedia-entry:
To the modern eye, the tank is hardly recognizable as such and appears as an armoured steel box resting on top of a caterpillar tractor. It has no turret, and its inconspicuous main armament is a fortification 75 mm Blockhaus Schneider, placed in a barbette in the right front corner of the tank. The right side had been chosen because the gunner had to stand to the left of the barrel to operate the gun.

The cannon type was developed from a 75 mm trench mortar that had been adapted to fire from a fixed fortification position by adding a recoil compensator and a gun shield; in this configuration it weighed 210 kilogrammes.

This short-barrelled cannon had a length of just 9.5 calibres. It fired the standard French HE Model 1915 75 mm shell but with a reduced propelling charge, shortening the length of the round from 350 to 241 millimetres, allowing for a muzzle velocity of only two hundred metres per second. This limited the maximum range to 2200 metres, the practical range was six hundred metres and the tank needed to close within two hundred metres of a point target to allow for precision shooting.

The gun has a traverse of 60°, a depression of -10° and an elevation of 30°. The ammunition stock is ninety vertically stowed rounds.

[...]

As the traverse of the main gun was limited, it had first to be pointed in the general direction of the target by the driver-commander swivelling the entire vehicle. To facilitate this, a small rectangular frame is fitted on the right side of the nose of the tank. Looking through it, the driver had a sightline parallel to that of the cannon in a neutral position. In practice, the commander had a too limited view of his surroundings through the small hatches to his left, front and right and had to resort to lifting his head out of his rectangular top hatch to observe the enemy.

Thanks, Arjen, that's helpful on the specs and interesting about the shortened 75mm ammunition. Anyone have any photos of one of these guns in action, perhaps comparing the short 75mm shells to the regular ones?

dan_inbox, thanks, do you have a solid source confirming that Canon de 75 court modèle 1916 Schneider is, in fact, the correct designation? I don't have any reference materials on French artillery but I do that there were lots of French 75mm guns including multiple different models by Schneider.

"Solid source"? Gosh, no. As usual my sources are only what I find on my hard disk.
I was only trying to be helpful thinking that maybe French isn't your 1st language. I will refrain next time.

Not at all, sorry if I offended you, I am very grateful for the suggestion and welcome your input, I was just looking for definitive confirmation as there are many guns with similar names. French is not my first language, but it is my second.

No offense taken.

Other applications: That 75mm cannon was used in the char d’accompagnement Peugeot 1918 à canon 75mm. This design tried to compete with Renault's FT, which was not found to have enough advantage over the FT to warrant production.

I understand that the Peugeot was proposed in 2 versions, the original char Peugeot 1918 37mm with a Puteaux SA-18 cannon, and the "“char d’accompagnement amélioré à canon de 75 Peugeot" with the BS, but I have never seen a photo of the 37mm version.
