I started collecting M1's about 25 years ago. Over time I accumulated a total of 17 through CMP rifle sales. Most are pure workhorses, well used and showing their age with dings, dents, etc.
Probably the prettiest one is a 1953 HRA with nicely figured (fiddleback grain) birch stock.
Best shooter is a 1943 SA that went to Denmark after WW2, used by Danish forces for years, rebarreled and restocked by Danish armorers (the Danish "crown" barrels are very precise indeed!). When I do my part properly that rifle will shoot 2" groups at 100 yards from the bench.
Rarest one is a "Win 13", one of about 10,000 Winchester rifles that duplicated serial numbers with SA production. I wish it remained all original, but like most M1's it went through arsenal overhaul during the Korean War.
Only caught one International Harvester, also an overhauled piece, but it is nice to have one from every maker.
Enjoy your new (old) rifle!
