but isnt the pistol at lower right, 2nd one up, a Walther P38?
“a P38”
Much depends on the year of manufacture and provenance. Post war models can be had for about $400 - $500.
Oops, missed that. Now I see that the P38 design was mfd long after the war even into 2000 (as the P1) and that example could just be “a high-quality used gun” on that basis.
