I was recently given a box of parts for is an original Rogers and Spencer revolver. The previous owner at one time before his death decided to take it apart but then was unable to reassemble it. The gun is in what I would consider 90% condition. However in going through the parts I realized that everything is there except five screws are missing: the hammer screw, the trigger screw , the two screws that attach the grip frame to the receiver and the small screw that is in front of the trigger guard. In playing around I discovered that the grip screw and the hammer screw have the same thread. My question is where can I find replacement screws. Dixie Gun Works lists some screw on their website but is unclear for some whether or not they are for the repro or the original. My guess is that the screws for the Euroarms reproduction were made with metric threads Any thoughts......?
