37mm Roth Trench Gun Round

[Weasel]

Hi All,
I belive this to be a WW1 37mm George Roth trench gun round, can anyone add any more info or pictures on the operation of this round. I have been told it would "bounce"
Best regards Weasel.

All empty and inert.

This is an Austrian round, but I believe they were manufactured by Stock & Co. in Berlin. The projectile, in addition to the main HE charge contains a small black powder charge, that is ignited on impact. Also ignited is a pyrotechnic delay. The combustion of the black powder causes a violent separation of the nose cone and main body, which in theory throws the remainder of the projectile back up into the air. The pyrotechnic delay then causes the main charge to detonate giving one an 'air burst' and thus achieving maximum fragmentation effect.

Regards

TimG.

Found a diagram. I think I have a description of it as well. I'll have a look in the morning.

I have 8 different projectiles in this case and have seen at least 1 other in another collection, The Italians copied this round in the bounching configeration, and I have seen 2 examples.There are slight differences between the Austrian and the Italian, all internal.I have not figured out how to post photos on this website, but if you send me your email address, I can send you some information. I have to search it out of the mound, but I have a copy of the Austrian manual around someplace. My email :greatotter@linkline.com

As a matter of interest the "bouncing" technology keeps being revived and is currently available from a couple of manufacturers in 40mm LV grenade rounds. It's much, much cheaper than the modern fashion for electronically-timed airburst systems.

37mm Rebounding projectile

Somewhere in my stack of literature I read a warning to the gunners not to fire this round straight into a hard target. One can only imagine why. Think about it.......
