Yeah, a few people have already asked me where my grandfather was on that day in 1963. Pretty sure my family name is in the clear
Thanks for the tip Tango. My gunsmith Frank and I did a casting at his shop. It is chambered for 6.5x52, which would make it an M91 (but a sporterized "Cavalleria"). Unfortunately, the bayonette is long gone. I tore my Grandmother's attic apart... Nadda.
It is taking multiple passes and some tough elbow grease to cut through some of this rust and attic grime, but it sure looks a hell of a lot better than it did. Frank is going to work his magic to see if it is operational. If it does fire, I'll take it out at least once. If not, oh well... still staying in the family.
