As a bit more history to this, my friend served as an officer with the Yankee Division in France during WW1 and then as a war correspondent during the Spanish Civil War and finally as a military historian with the 1st Armor winding up in northern Italy by the end of the war as unit historian. He carried his WW1 1911 pistol through out the war. I have is entire WW1 rig, 1911, holster, Mills belt, and ammo pouch with two WW1 mags. Clearly didn’t shoot anything during WW2 as the mags in the pouch are full of 1917-18 cartridges. I suspect the 5MD might have something to do with military historians, today they are called MHD officers. at any rate still looking for the place he picked up the CYQ.
