This one has been redone for sure The serial number starts with Y so I thing 1964. It has some custom work for sure along with a strange trigger. Anyone know anything about the trigger or gun? I have past it up several times. He was asking $550.00. It is a pawn and gun so I traded a knife and a pool cue plus 215.00 cash. I would say I have about $500. in it as he came down some on the gun but gave me less than retail of course for my stuff. Anyway I was happy with the deal and knew this is no collector, but other than one ding in the butt stock and the missing bulls eye it is in nice condition. The remodel job is not my style but looks to be done well. Of course I am a sucker for the Redfield peep sight as well.
