Newbie here. Sorry if I'm posting this in the wrong place or manner, but I have a P.38 I want to sell, manufactured July 1944 Spreewerk, numbers match on frame, barrel, slide and locking block, and I believe all correct acceptance stampings etc. Very good condition, with an original P08 holster and two period original magazines. Owned more than 50 years. In Texas, how do I sell?
