You Sir, have now been infected with the disease known as Garanditis. One or two are never enough. You need a Winchester, and H&R, and IHC made ones. then one of the post WWII rebuilds, then a match rifle, and as the disease gets into advanced stages it demands an M1C or M1D or both, A Navy 7.62 conversion, and Italian BMB or Beretta copy, and the fatal holy grail: the early gas trap model. Me, I am about half way there.
PS Very Nice rifle for a 1st purchase. If the bolt and barrel both date to the same time period as the receiver and stock, then: Heck I would restore it to original configuration. But, If you do, call it a restoration or corrected gun, NEVER call it as issued! As issued means it has all the exact same parts it left the factory with.
As suggested above, go to the CMP forums, buy the books by Scott Duff, Bruce Canfield and others and join the Garand Collectors Association, www.thegca.org. If you are a GCA member and really want to know a lot more about the M1, you can buy books 1 through 5 (so far) of the best info from past GCA journals.
