Actually, the finish on this particular gun is not Bad at all for a "CYQ" Spreewerke. Keep in mind that they never left the factory in much better condition than this one is in, so you have to evaluate it from that standpoint. The bluing on it is pretty much intact and aside from the disturbing Grip damage(which can be easily swapped out) there really is not all that much wrong that I can see with this one. The photo's do not show a Magazine in it, however, and this is a considerable concern. As Mike said, does it Come with a clip and does the serial number on it match the gun? The spare clip should also be of period, as has been said. And, of course, a holster is absolutely needed.
I doubt that it is falling apart, despite the many times heard comments about how Spreewerke guns were virtually dangerous to shoot. I had one myself for quite a good many years and never once had a problem with it. There was always talk-even back then-about the firing pins crystallizing in them, but I never ran into such a thing on the ones that I examined. About the worst I ever found with them, was the lips of the magazine were sometimes sensitive and easily deformed if not careful, and thus would feed incorrectly. So...don't drop them on the cement, is all! lol But, bottom line being, for $550 dollars, I would want the 2 magazines and a decent holster to go with it(Hopefully with the 1st clip having a matching serial number to the gun).
