I was making my rounds in north idaho gun and pawn shops and found an rc to buy. while I was looking at the levers I spot a gun that did not look right. I, at first glance though someone had cut back a new looking mountie and I instantly asked to see it. I did not know a TDS came in straight grip or that it had a safety. This gun looks brand new and has the carrying case and they are asking $750. What is this and what is it worth? collectability?
