It appears the original poster has the hammer Biks(hahn Büchsflinte for the language intolerant) Borovlje Platform up for auction. It appears the extractor component might be a replacement?

Anyway, Jani and I were tossing emails back & forth on Franz Sodia in the 1920s & 1930s and how Franz Sodia was heavily promoting the 6,5X70R Sauer(feel free to add whatever moniker you fancy) during these two decades and that the cartridge was offered for-sale up to maybe the 1960s? So what characteristics make this pencil cartridge so acceptable during the time? Low Pressure? Meets the Criteria for all the Game in the Region? Low Recoil? Ease of reloading possibly coupled with a small amount of powder? Why would Franz Sodia go so far as to have his own headstamp and possible a proprietary round? Now Franz Sodia carried a lot of weight in Borovlje as his offerings often lack a full regiment of marks and he seems to have had a bias w/ the Ferlach Proof Facility?

Hochachtungsvoll,
