Very interesting thread. I own one of these "Eaton's" Carcanos. I have one casing that was fired in the rifle and 13 loaded Norma rounds.
The fired primer seems normal enough. There is "6.5mm" stamped just behind the rear sight. Can anyone tell me if this means it is chambered for 6.5x52 Carcano or 6.5x54 MS? I will take a pic of the fired round beside a loaded factory round for comparison.
No, I wasn't the one who fired it! The fellow I bought it from had it registered as a - get this - Jap Army Rifle. That is what the marvelous registration certificate stated! Geez, no wonder people are blowing old guns up!!!
