Yes, the report stated that the cases were traced to the individual, two, Thompsons. One had left a distinctive mark from firing pin on gun #2347 and ejector from gun #7580. Looking back at the print out one gun fired 20rnds. and the other 50 rnds. An average of 10 rnds. each dead man. The Chicago "Mob" was always very efficent!
The Deputy who was watching the disply told me they were allot of fun to shoot.
Another point; Report stated the cartridges were all from the US Catridge Co. and "they were manufactured only between July 1927 and July 1928". So the guns must have been in the original Thompson .45 cartridge, which is longer then 45 ACP?
