I want to thank all who have taken the time and effort to answer my request.......greatly appreciated.
I'll post pics as soon as I can. I don't have the presentation case,only the tools. I bought it from a pawn shop back in the late '70s for $325.
The "S" serial number intrigued me. The gun is in excellent mechanical condition but does not have the deep polished blue quite like you'd expect but does have the original diamond grips. The grips are definitely more comfortable than the later models. I don't think it has been reblued.
Thanks again to all.
