Looks to be a model 744. 8'',vent heavy in .44 caliber. Pachmayer grips. Does it have any of the tools to change the barrel? Or original box? As is, I'd say at least $500. If the original box and tool are with it, close to $600. Is it a Monson,Ma or a Palmer,Ma manufacture? Most Wesson fans like the Monson models better, as it seems the quality control was better. I wish I had my old one back, as it was, without a doubt, the most accurate revolver I ever owned. A friend of mine talked me out of it, and now he refuses to sell it back to me. gypsyman
