Thanks Mike.Dan, I may have information on my laptop at home. I will check this evening.
There used to be a great website (7.62x54.net) for info on Mosin-Nagants, but it disappeared a few years back.
I cannot access the Wayback Machine website (https://web.archive.org/) at work but they will likely have captured copies the above website before its demise. Just search on the above link at that website to what is avialable.
Otherwise, there are a few other websites that have some of that info...such as: https://www.m9130.info/markings-and-proofmarks
