Hmm, thanks for that. I thought the number alone would give a more precise date, so I did not mention that this is a 3-screw gun. Based on something I saw elsewhere, I gather this would make it a 1962 or later gun. But that doesn't seem consistent with a higher serial number being made in 1960.
What I'm really trying to determine is whether this gun was made in 1965 or before, so that it would qualify as a C&R I could buy directly. Are the published serial number lists just not precise enough to do that?
Thanks again for any help.
