It seemed to be a good day to buy a gun from a WWII vet. (The same guy I bought the Dreyse 1907 from at the last show; he kinda remembered me, towards the end.)
It's a Great War-bringback Mauser 1914. It's been re-blued, albeit nicely, and needs a striker (I'm guessing it probably spent time in someone's shadowbox: "It's okay, Edna, I took the firing pin out. The grandkids can touch it.")
I probably could have chipped a couple more bucks off the price for the absent striker but, hey, he's a WWII vet, and as far as I'm concerned, the events of this day sixty-six years ago earn him a couple extra bucks in my book.
