gyman98,
What you have there is an average mid War Walther. High production figures in 1943 and a quite common P38 (about 150 000 AC 43 P38s produced). Bore condition would be critical for establishing value but at best you have a $350-425.00 pistol (depending on the buyer) For an original P.38v, spine proofed single E359 mag expect to pay $75-100.00 (this would not raise the pistol's value but just make it ``correct``)
