Hi browningautorifle,
the revolver you`ve seen was a "Reichsrevolver". Cal. 10,6mm .
The base for the development was a S&W Russian .44. He must give the revolver to the officer of his guards ( US Army ) and i think he would found a new owner somewhere. Görings revolver was luxury model and not a simple one like this in the pic.
Regards
Gunner
