Picked these up in Nova Scotia this passed wknd.
Shirt stamp is inside right and says
MILLER & GABBE LTD
JACKETS, COTTON DRILL, O.D. 7
and the stamp is 669 over the arrow over an S and an I (I think).
and that stamp is inside left on the front pocket material and says
FEDERAL PANTS INC.
Trousers, Cotton, Drill, O.D. 7
Funny to see an NSN and size (at least the first 4 digits) the same as today.
