1938 S/42 query

[Robert W. Simms]

Hello:
Thanks to all of you for the willingness to share your knowledge. This forum is great for a neophyte like me. I have the opportunity to buy a 1938 S/42 Luger "shooter". The gun looks very nice as it has been recently re-blued. Prior to the re-bluing it was buffed to remove some light surface pitting and this has softened some of the detail lines and made some of the markings less distinct. The only strawing left is on the ejector. The bore is in excellent condition; no pitting here. All the numbers on the gun itself match, although the grips are plastic aftermarket, and the mag is a correct WW2 aluminum-bottom mag but with a differing S/N. I was allowed to test-fire this Luger. It is very accurate and functioned flawlessly with several brands of ammo. I know that the collector value is shot, but it would make a very nice shooter. The seller wants $700. The price seems a little on the high side to me but I am soliciting opinions here. What say you?
