Newbie S&W collector here... so I offer my comments with that caveat. I would consider $450 very reasonable for a good shooter like this. I just picked up her identical twin sister who was on consignment at my LGS yesterday. Very slight blue wear at the muzzle but aside from that the finish on...
Got one to add to the list:
S/N V71904, Ordnance bomb over 385 on the butt (local inventory number of some sort?), no other unique markings.
Assume it was manufactured in 1942... nothing else known about it.
