In more research I’m thinking it is a grade 1 custom shop gun. It was this guys fathers gun and he bought it new and has his initials on. Says never fired. I’ve got to travel 2 hours to look at it but I think it’s worth a look if I can get him down in the price. He is wanting 1200 and I think that’s high. (Maybe I’m wrong)
The 8mm seem to be really hard to find.
