were all m1 d's and c's springfields?

Ed, then you must believe that all the Tooele 1960s marked M1D rifles are rebuilds rather than original assembled M1D rifles, right?

M1D rifles were built in the fifties and sixties as sniper rifles for Guard units (go figure!!) and many were put in storage. Hence the M1D lottery rifles we know from DCM/CMP sales.

Other rifles were assembled from parts, which could be ordered through supply in the fifties, so many different builds may confuse issue for collectors. Units sometimes built their own if an armorer had the parts. More confusion.

NO M1D rifles were issued to snipers in WWII, as they came along too late for war effort.

Many rifles were other than Springfield and you will see them from time to time. Since the rifle's construction requires no machining of receiver, many have been built in the aftermarket world, and they are just as valid an M1D if constructed with real parts. Experts will advise you if your rifle is a real one or a parts rifle.

I also recieved a Winchester M1D in the 1st lottery. Splg barrel.
