I have a family heirloom that has been handed down a few times. The story goes that this piece was carried by a family member while riding for the pony express. I have a set of saddle bags that go with it as well. It is in rough shape at the moment and is not useable. I believe there is a broken spring inside since the hammer just flops around freely. My plan is to have colt pull the archive records for this but I am not sure of the model. So I have 2 questions. 1 what do I have? 2 should I get it restored or will that "ruin" the gun.
