I've owned two nickel 6" Smith model 57's, both with S prefixes on the seriel number. I currently have a deal in the works for a 4" blue Smith model 57 P&R. The 4" blue is the one I've been trying to get and has eluded me since the mid '60's. With any luck, I'll own one soon? Forgotten or dead, I don't think so? Hopefully Smith has recently awoke to the want of their customers for the .41 mags., with the introduction of the new 57 M/G?
