wasting time on gb, and came upon this pretty unique offering.....https://www.gunbroker.com/item/1049693206
seller identifies it as a "hercules action", and states it is early 20th century origin....then totally fails to provide any photos of proofs - and says it is either 9.3 x 74r, or "possibly 7057 cartridge"....
i can see enough of the bottom metal in photo #12 to feel sure it is a franz jager herold action, and i have understood these were built as double rifles. also, visible are the late 1911 (zella- mehlis) or mid 1912 (suhl) nitro mark on the sides of the chambers. can't make out details enough to indicate cartridge, but remainder of the barrel set look mighty slender for 9.3's.
appears it was a neat light weight double rifle, and in 7 x 57r would be delightful i'm sure....also sure i'm glad not to have been in the neighborhood when it came unbuckled.
best regards,
tom
