On the fuzzy photo of the barrel flats there appears to be something just above the flats stamped into the steel. What does that mark say? Also, I see no crown/nitro unless it is on that edge. If the gun had been sent back for reproof there would be a repair mark which I don't see. We also need a photo of the action table to see what is marked there other than the serial number almost visible in the photos above. There is no question this is a set of German barrels. I think it remains to be shown where the action came from.
