42 luger

Bob do you live close to Wisconsin? My grandfather had his bring-back Luger stolen from him in the early 70's and I have made my main mission in life to try to find it, as hopeless as it sounds! Anyways if you live close by I would be interested in meeting you and maybe seeing this Luger. I realize this sounds desperate, but I must pursue any possible lead. I can rule this one out right away if it has an import mark, does it? Any help you can give me Bob would be much appreciated. Thanks. PHIL
