I just picked up the holster in the pictures below that was advertised by the seller as a S&W Wolfram FBI holster model 01-1034. I don't have it in hand yet but I picked it up based on this forum thread:
Couple of Smith holsters...need info
This holster bears the S&W logo and is also stamped with a 5. Based on the thread above the 5 appears to be Wally Wolfram's size numbering system but I am really looking to confirm what size S&W this will fit. Seller said a 4" barrel 686. However the 686 was not introduced in late 60's early 70's when I believe this holster was made. The thread above states possibly a 4" M&P revolver. Does anyone know anything more about this holster and what revolver it will fit? Thank you
