Hello all. I just recently purchased a Luger from a lady whose husband had passed away and she didnt want it in the house anymore since she knew nothing of firearms. Actually I bought several firearms from her and included in the sale was a 1916 DWM luger in what looks to me like alomost new condition. Her husbands older brother supposedly got it during WW2. It has not been reblued and the finish is practically flawless....no scratches, pits or wear on the finish. I have never owned a Luger and dont know a lot about them but I do know that it is a numbers matching pistol since all the part numbers are the same. Included in the sale was a Remington-Rand .45 ACP 1911, an L.A.R. Grizzly .50 AE, an import Belgian made FN-FAL in 7.62x51 and the Luger. I got all this for the price of $550.00.
I know I made a good deal and even told the lady that the guns were worth more than that but she just didnt want them around the house. Could anyone teel me an approximate value of the Luger or how I can find out more about the pistol? Any help would be appreciated. Thank you.
