National Match DCM Original?

[CJS57]

Devil, Thanks! It does have the 2 screws so I guess it is now very well established that the rifle ( in it's current configuration) is 1) An original 1959 SA NM reworked by an Air Force team. Or, 2) It was built from scratch by an Air Force team using a 1959 barrel removed from a real NM.

I think I will sent the letter of inquiry to the CMP to find out if the receiver was ever part of Springfield National Match rifle. Obviously the rifle is much more desireable to me if it at least started it's life as a SA NM!
