HI All again :-)
I got such a case, probably incomplete. Head dia = 0.601, 1.237 long. Brass case. No primer. Deep hole under Berdan primer - (0,169). Inner insert with a fire hole. Found in the River Thames in London. HS = ABRAHAM & BAYLISS BIRMINGHAM PATENT. I found a description of Abraham & Bayliss’s patent, but nothing more. Caliber? , Length? I appreciate every information
This is the last question :-)
Thanks
Rufus
