P-38 Question

[ripcord810]

I have a man wanting to trade this P-38 for one of my pistols. My question is about the P-38. I know little about them and trying to see if this might be one I want to add to my collection. Here is the information he sent me: "This P-38 is a Mauser built in 1943. It was never issued or fired, all numbers match and in the presentation case. There is a sheet of paper in the case that explains how this handful of unissued P-38’s were picked up just prior to the wars end. These rare few are offered by Mitchell’s Mausers to collectors and run about $3400 when found. Waffenstamp Proofmarks are 135 coded with the eagle and swastika, and quite rare also. 100% guns, as this one, are seldom seen. The black walnut case is very nice and numbered to the gun".
