Hotchkiss 25mm and 37mm cases

[earni74]

found these 2 shell cases today, the 25x194mm Rimless (Experimental)

Does anyone know the significance of the circled (T) stamp on the 37mm, i have looked through my books/papers but to no avail

Thanks
Mick

I'm not sure that your 25 x 193 rimless is experimental. It was the first of the 25 mm Hotchkiss rounds, appearing in around 1933-4 (followed by the rimmed 25 x 194R a year or two later, and the 25 x 163 rimless a couple of years after that). It was designed for an automatic anti-tank gun, which was advertised in a 1934 catalogue. The gun was certainly built, and there are rumours that some were sold, but I've not been able to pin that down.

Hi Tony, i did read somewhere in the past that it was experimental and that has stayed in my mind ever since, i'm happy to be corrected, i will continue to search mainly for the correct projectile type
Thanks

Here is my 25x193 Hotchkiss.
The group photo shows the case differences.
Projectile also differs from the Jap one as the steel body also unscrews.
