at auction this year in IAA there were several photos of 7.92x86 cartridge, I am looking for the author of the photo or buyer. Maybe better quality photo? :) [Permission to use photos in publication.]
Does anyone have a case 6,5 mm in the collection, i think 80 or 86 length, so probably 6,5x80 / 6,5x86 [I do not have certain information about the cartridge, the probable length]. (high speed/antitank/PL experimental)
I am looking for a contact to Mr. Jost Burkhard Anderhub (for info about 20 mm ammo in his book about 20x138B).
