My friend has a Walther PP that he doesn't know much about. I have been researching the gun and it is a "Manhurin" and somebody has defaced the slide to remove the label to the right of the manufacturer's mark and extends to the slide. The defacement looks like somebody to a metalworking tool, like a router and "scraped away" the engraving in a very neat oval pattern, leaving a "white oval" on the slide. They also ground the upper and lower portions of the grips to remove any "Walther" labeling. The serial number on the slide is intact and the rest of the gun is in excellent condition. I'm wondering why anyone would deface the gun in such a way, I've never seen this before. Does anyone here have any idea why this was done? Can this defacement be repaired or do we need to find a new slide? I've just begun to look for a slide and I haven't found one yet. I would like to repair this damage, if possible and put the gun back into the condition it should be in. The grips should be easy to find and I'll replace those. I'll post some pictures this Friday, as I'm working out of town during the week and the gun is not with me. Thanks for any insight you might be able to provide!
