It is a longshot but if you post photos of the gun, including clear photos of all the markings and the rear part of the firing pin (if you have it) it would be helpful. What springs are missing? Not all old guns had springs to retract the firing pins. If the missing springs are in a "lock" and you have broken pieces or the same spring in the other lock, post photos of them also. Many of us have old parts, ID is the problem. Drew Hause is correct that the main value is family history.
