DAQ M1 Clips

Does anyone know the dates that Dominion Arsenal Quebec made M1 Garand clips?

I can’t get to specific to dates, but I was given an M1 clip marked DAQ by a former employer who attended Norwich University ROTC in Vermont in the late 1960’s or early 1970’s. The clip was used there as part of the rifle training. So, they were around at least as early (or late) as then.
