Model 1921 misssing in action.

Frank , I have done some digging and here is what I have come up with, Caliber 9MM.The toggle was marked DMW and if my memory is correct, the top chamber marking was Portuguese Naval Marking. Mac: if your reading this, There were no capture papers. I have letters written for my father by his supervisors in the aicraft company he worked for stating that the weapon was in his possesion prior to that requirement.(I will check the dates of correspondence)To my knowledge the luger has always been chrome for as long as I can remember.(at least in 1955 in Dahran Saudi Arabia). We didn't return to the states til 1961. The Fire Arms permit to allow him to carry the wweapon in India listed the weapon as model 1921. All Serial numbers matched, on all parts (3611 or 11) and the clip also. I can not remember if there was a proof mark, though I'm looking at various marks to see if something sticks in my memory.The Grips were checkered walnut (I think) painted black and worn through to the wood beneath. Barrel length was 4 inches. It had a hold open device on the last round. There was a marking under the safety lever that began with a B... some like borschadt ???? I'll keep digging and racking my memory.... I had not had it out in a long time, but as many times as I'd cleaned it, you'd think something would stick in my mind...Many thanks for the help from you both. look foward to hearing back from you, Jim Kochan
