The date code you spoke of is a bit confusing to me. There are 3 letters (RYY). The YY looks like they were stamped together, but the R looks a little different. If the YY is correct it dates to 1952, but if it's the R it's 1968. Also, the R could mean November 1952. I took a pic if that helps. Any ideas? Thanx for your reply.There is a code on the left side of the barrel. You can find the info somewhere on the web.
