Wow nice gun! But, ya if there's no sentimental history there, I'd sell it for something you can shoot and enjoy- and buy some bonds or something to give the kids for college money with the change.....
IIRC these things aren't considered safe to shoot much with modern ammo anyway?
Not to get off topic too much, but a guy at my work just found an immaculate Baby Nambu in his late fathers closet in a shoe box, complete with holster, cleaning kit, and spare mag! Not being a gun guy, he had asked me to take a look at the "Japanese Luger" they had discovered and was it worth anything. Once I told him what he had and what it was worth, he sat down with the family and they all agreed to keep it as his dad was a WW2 vet who had rarely talked about the war and hadnt left much else for the family to pass on. It is now in a Lexan case with some pictures and the few other mementos of grandpa- its a really touching memorial to the man and his service.
