You asked for it, here you go.
Vince, my brother and I spent all day fixing these 2 things. The images I posted are not the fixed/cleaned ones though. These were taken before we started cleaning.
The long gun will defiantly work, the lock is very strong and it sparks very well. If the barrel doesn't blow up when shooting it, it will be a great gun.
The small one is good too, but we need to replace one barrel band and the lock is broken. The hammer is to close to he pan and doesn't have enough energy to let it spark. Addionally, it can be fired from half cock, which is not very safe.
