Strange things can happen. My buddy's cousin lucked out just a couple of weeks ago when an estate was cleaned out. The widow gave him "an old pistol", which turned out to be a WW1 1911 in a tattered mailing box from Rock Island Armory. If free 1911 can happen, why not a $325 Luger? Definitely worth a follow-up IMO.
BTW: The 1911 is in my safe now...
