Help please divine M1-A

[TxHolly]

I have 2 M1 and 1 M1-A. I'm trying to determine if all the National Match M1-As manufactured with 3 digit serial numbers like 0001XX would definately be a Divine gun. Purchased in April 1970 with custom stock and accuracy. Not seeing any markings on barrel and am afraid to take it apart.

If not stamped on barrel it isnt a Devine "build"

+1 to Orlando.
Check the underside of the barrel around the gas plug area to start.
