... got some pictures. Sorry for the cruddy shots but my camera stinks at closeups...
It's definately refinished. Nearly all of the markings have been ground off, top of the toggle, top of the chamber (date) and right front of the frame (proofmarks). It's been machined along the safety marking and has absolutly no matching part numbers. He says these are also replacment grips - by him. Not sure if he has the originals (not that it would matter). Underneath the barrel it's marked "Made in Germany". There are two proofmarks, the number 3 and the number 20, each in a box.
As I said, it's refinished. It looks pretty good, considering all of the markings have been ground off. The blue job still looks fairly nice though there are some areas of minor wear. You can see some old pitting that remained from when it was done. I'd rate the overall finish at about 95% or better. The trigger and all strawed parts were blued.
Sorry if the images aren't sized correctly...
