Indeed & all the Kombos have 62 cm tubeset length, are quite similar in shape & form, have the 1/2 Pipe Side-Frame Reinforcement & according to Axel E. they were made by Christoph Funk, but the bulk of them passed thru the Z-M Proof Facility and one just doesn't see Christoph Funk's mark. Of course it could be hidden & gearing up for the 2nd Major Disagreement in Europe, the Suhl Proof Facility might have been very busy with instruments of War?

Axel E. also notes the following:


>>The DEVA once listed two pressure tested loads:
70 gr Hornady, 51.5 gr IMR 4831 for 3540 fps
77 gr Gehmann original, 53.2 gr IMR 4831 for 3500 fps
As the cartridge is known for Secondary Explosion Effects, downloading is advised against.<<

Hochachtungsvoll,
