I just bought an early (1066XXX) Winchester M1 carbine. The previous owner has had it for ever and only sold it because of ill health.
It appears to be all correct and unmodified except for the stock which was replaced years ago when the original one broke.
The odd thing is that the barrel has a small "W" 1 5/8 inches aft of the sight but NO proof mark anywhere on the barrel. There is a mark that could be a punch mark but not sure. The bolt and receiver both have the punch marks.
Any ideas??
