My dad has 2 WWII era Nazi marked pistols. One is a Walther PP and the other is a Sauer und Son 38H. Both pistols are in similar condition. I am hoping to inherit both from him some day, but it looks like he will be giving one to his grandson (my nephew) for his graduation. If he decides to give one to my nephew, I get to choose which one will be left to me. My question is which one do I choose. Both were acquired by my dad in exchange for work he did, so there is no family history with either one. I do like both of them, but as far as value, rarity, collectability, which would you choose?
