Martin , Thanks so much for your post.. Its a dangerous fake. It could easily be turned into a ground dug HR and the defect might not be seen. Any newly turned up HR must be scrutinized fully..

I just checked their up-and-coming auction: https://www.ratisbons.com/59th-contemporary-history-auction?searchterm=ring

So far every PP ring is a fake. There is a HR to an infamous personality, Fritz Freitag. Engraving looks a bit light.... Anyone else seen it?
