Sorry it took me awhile to chime back in. I appreciate all the posts. I'm leaning towards it being a Russian version the cylinder appears to be around 1 7/16 in length. As far as value it was worth it to me what sold me on it was the low 4 digit sn and the fact once I got it home and did a good cleaning on it including the packing grease still on the cylinder post and found it to be a fine working weapon. I've been a spinner shooter for a long time with the exception of the solid hammer I will take the action of this pistol over most modern spinners. I will be shooting this gun. Can't help to believe that maybe one box was ran through this gun then put up dirty in grandpas saddle bag
