was rummaging around in the attic and found a little Japanese 410 single shot. I assume it was my stepfathers. Says "Shinkosha - Japan .410 3" chamber" on one side of the barrel and on the other it says " FIE - MIAMI, FLA. MODEL SB2B". Cant read the serial number. Looks like a piece of crap to me but what do I know! Anybody know anything about this little thing?
