Thank you for the G. Roth information.
The second question has nothing to do with G.Roth! sorry for the confusion.
I am trying to identify an auto pistol round, See picture. [scans, not very good, bad lighting, but the best I can achieve at the moment]
case length = .685
projectile = .315 heavy crimp into cannalure, so may not be correct ??
rim = .345
slightly tapered case
O.A.L. = .973
Just looking at measurements on a list of metric cartridge sizes I have and guessing, the sizes of the 8x17.5 seemed to fit, but I have never seen one to compare, and it too might have a more common name as this is only a copy of a list put together by collector, from actual cartridges. but misses some info, such as whether they are bottle necked or semi rimed etc.
Thought if there was a U.S or English designation for this cartridge it might help me.
Just editing again, compared it to 32 ACP, 35 S&W AUTO and 8mm STEYR but the difference in size would eliminate these.
