I'm a 'babe in the woods' as far as being a novice who would like to have a nice WWII period M1. But with all the many variables, such as serial #'s, all the different manufacturers, manufacturing dates for the many suttle changes that were made etc, it sure gets confusing. The more I think about it the more I'm thinking I might should have grabbed the Quality Hardware M1 at the gun show Saturday as I have since found out it had the desirable round bolt and 'I' shaped oiler indention in the stock. I'm looking for a nice shooter, so I'm not obsessed with trying to find a perfect period correct M1 carbine. I've been told by the wife to start a 'M1 fund', do a lot more research and I'll probably find 'the one' in the next year or so, which is probably good advice.
