Was in the local shop (Charleston, SC) this evening and spied a Colt Lightning express rifle in the rack. The guy behind the counter said it's 40-65, but the bore looked more like 45 cal. Action is locked and I don't know why, and it has some replacement screws. Otherwise it's all there and in decent attic condition. They have $2000 on it and would probably deal. I would have dickered with them, but couldn't do anything until after Christmas. PM me is you'd like contact info. I have no connection with the gun, other than it would be nice to see it get a good home.
