I will try and measure tonight as I will be in the shop working with my son on his Cub Scout regatta boat.

This is why I like the old military firearms as it is like a puzzle to figure out what happened with it. I do find it interesting that the barrel was replaced as the rest of the rifle is in good shape very little rust in some of the cervices that I was able to clean up with Corrosion X, cotton patch and elbow grease. Wonder if it was shot and not cleaned then the bore was super corroded.

Thanks
Martin
