Raimey,
I really don't know what you are referring to when you mention Gebrauchsmuster Nummer 134556 from 3.03.1900. Where can I find this description?
Herr Amerikaner
I have relied on the seller's representation that the barrel length is 50 cm (which seems awfully short), but I dredged up what little algebra I can remember after 57 years and applied it to the photographs, with mixed results. Assuming the length of pull of the stock is about 13.5 inches, then the barrels probably are 55 cm, as stated in the catalog. This is still three inches shorter than Churchill's famous XXV shotguns, one of which I once owned.
The rifle barrel caliber is 8X57IR, for which I am amply supplied with components. IF there is enough metal in the barrels to allow it, I would like to lengthen the shot chambers to 70mm. Otherwise, I will just have to draw on my limited supply of 2.5" ammunition.
