Ah, I should have typed Taubenflinte/pigeon. Yeah, at 6 lbs it is a bit light but it has all the characteristics of a Taubenflinte. A chopperlump tubeset is the exception in Suhl. It may be that more chopperlump tubeset originated from the Zella-Mehlis region than Suhl. I consider it a very good deal as I don't think you could get an O. Geyger for double that price. And it just reeks of quality. 2 5/8" is more like it and it memory serves me right(please correct me Mike Ford if I'm wrong) that for scattergun chambers a 5mm difference in the longitudinal direction would warrant a stamp of the next dimension. So a 65mm chamber could be a bit longer and still be considered a 65mm. Or it may have been that most were closer to 67.5mm than 65m and it was when a chamber exceeded 67.5cm that the stamp switched to 70mm. Ford has told me and I didn't pen it on the back of my hand. Also past 70mm, there was an equation for pressure increase per 5mm.

Anyway, I'll say that at a distance you could put this one beside a similar O. Geyger and practically no one could resolve the difference.

Post some images of the marks from the area forward of the flats to the forend hanger if you get a chance.

Kind Regards,
