Hey folks, I'm looking for a gunsmith or competent gun aficionado with a working knowledge of the Czech DUO. It's a Browning type design .25 cal made 1942 in Czech under Nazi occupation. Problem: I took mine apart too far. I was stupid and impatient and didn't videotape or note the order I disassembled. There is a small spring I cannot fit correctly and don't want to be even stupider firing the gun without it. Anyone here that knows how to fix this problem? I'm looking to come to you and pay you for your services, not looking for a handout or an explanation over the internet. The firing pin was broken upon purchase from the pawn shop, but a small company makes copies. I was thinking I'd buy the WOLFF spring pack for the DUO and have whoever helps me with this change everything out for me. Thanks in advance!
