The markings on any military aircraft denote it's country and often it's squadron or wing.
You need a professional appraisal
be honest with her and ask her out maybe for coffee in the beginning No way to answer your question without a detailed description of all markings.
Need a detailed description of all markings, finish, etc. Range could be from a few hundred to multiple thousands.
a lot of money! (I would like to have that!)
100-1000 depending on EXACTLY what you have and its condition/orginality
Try the P38 forum.
range rover p38 manual
although a P38 fires the same ammo as a Luger (9mm) it is not a Luger. It is a double action pistol that replaced the luger before wars end.......value of P38 can be checked by going to 'gunsamerica.com' and scroll or seek P38...................
Ruger never made a model called the P38.
Ball park range is $500 - 800. more if it is a dual tone
$600-$900, depending on markings, accesories, magazine, holster, etc.
If you are in possession of a genuine World War Two-era Walther P38 pistol with the markings you describe, a bird with outstretched wings, whether engraved into the metal of the slide or carved into the wood of the grips, then you are very likely looking at a pistol that belonged to an SS officer or NAZI party official. If the marking you describe is inside of a circle, centered directly under the "bird" with outstretched wings, it is probably the swastika. The universally- recognized symbol of NAZI Germany, which was in power from 1933 to 1945. Such a firearm, if it is authenticate to be an original would be a considerable collectors' item in high demand.
