Wilhlem Kelber looks to have performed all the tube work with the "K" encircled by the "W" along with the script "W.K." initials. Pending consideration a few measurements like the rim diameter & base diameter I'd say you have the 8x58 Sauer which also had the designation 8X57R. Also if the bullet diameter was 8.2mm it would almost exactly fit the 8x57R Express or 8.2 X57R(Hagen). The 8(8.08)x58 Sauer would fit well with the Roux action and some free advice would be to never get a 8x57IR cartridge near the drilling. The "Crown" over "W" on the scattergun tubes indicates constriction. The "16" stamps give chamber info as well as black powder proof. Can you get a good pic of the "St" stamp? When I have more time I'll stare at the marks a bit more. Do tell the whole story including purchase & delivery.
Kind Regards,
Raimey
