Rocketeer Buckle?

[BROTHERFOSTER]

Just got back from a gun show. One vendor had a whole table of military surplus. Picked this up for $15. Before you ask, it was the only one that they had. Don’t think it’s an exact match for a Rocketeer buckle, but pretty close.

They choose that one because it's flat as to not make the jacket bulge when wearing the pack
