Thanks! I had a M97 in Vietnam circa 1964 along with a couple of other guys, maybe 4 total. We didn't pay much attention to them and used them for inhouse protection and not in the field. Had one come up recently for sale, parkerized, so it had been rebuilt, and was looking at it. Manufactured 1948-49 from the serial number, so far all correct. Where were they located on the stock?
A number of the Special Forces A teams we supported had them also. Some interesting stories came from those guys on their use.
