A fantastic firearm for sure. Having said that, there is a lot of pistols attributed to Third Reich personalities which goes on auction each year it appears. Some ten years ago i was offered a supposed Göring walther, not identical to this one but still nice. It turned out it was engraved in the 80s and ordered by a dealer to retail as a genuine item. Of course, the Walther was genuine but the engravings were not and it never belonged to Hermann Göring.
For one to buy a firearm like this, i would expect 100% watertight rock solid provenance back to 1945. And, the ring which is included with the sale of this gun is not the ring it is claimed to be. They claim it's the well known ring worn by Göring mostly during the 1930s, this is not correct and period photos shows that the ring Göring wears is a different one. I'm not saying the one included with the gun isn't real, i'm only saying it's not the one claimed to be on the photographs.
