During my stop at a local shop I saw a Mod. 37 RB with a 3 inch barrel. The gun is in great shape has a box and papers. I am not sure if there was a turn line. The price is $450 and I am not sure if he will negotiate. Never have seen a 36 or 37 with 3" barrel. It would be a safe gun but a carry or shooter. Let me know, THANKS.
