According to the serial number it was made in 1958. I picked it up at an estate auction a few years back. It has the extended forearm, checkering, and a vent rib modified (choke) barrel. All original except it looks like someone put a new butt stock on it at some point. Grain and finish is slightly different but correct for a model 12.I like the old classics but they are getting really hard to find at a reasonable price
I wonder what the New In the Box price was when they were sold? I'll bet it was a lot less than you paid.
Mine was given to me as a wall hanger, and I rebuilt it.
