I've sold nearly 100 of them (and I still have more!).
The pre-1942's and HEX receivers have a better exterior finish, but don't necessarily shoot any better.
Laminated stocks are "different", a little prettier (IMHO) the straight wood stocks stocks, but not necessarily any "better".
All that said, I think these rifles are the center fire rifle deal of the decade, if not the century. Where else can you get a powerful, reasonably accurate, historical center fire rifle, 100 rounds of ammo and get change back from your $200?
