I just got back from my mother in law a Smith Model 36-1 that I loaned her several years ago. This Smith is Blued with wood handles 3" barreled 38 cal., 5 shot. It has some rust along barrel, but in otherwise good shape. Some one offered to buy this Smith from me. What is possible value? I can not post pictures right now (not at home). Will post when I can. Also on a side note, would anyone kow how old this revolver is? I can get serial number if needed. Thanks ahead of time.
