have again a remarkable piece on egun http://www.egun.de/market/item.php?id=3995660

a double rifle drilling two barrels in 9,3x74R and a 16/70 shotgun barrel made by Bühag/ Suhl, gunmaker Kessel for the Leipzig Zoological Garden in 1965 as a last argument in a dangerous situation. the 9,3x74R was than the biggest rimmed cartridge availabale in germany.
the drilling have three lock's, a Zeiss Ziel 4 on claw mount and a forward set trigger.

looks new, great price for such a combination
remember this is a true handmade piece

zoological gardens have allways some big bore rifle's for such a tragic incident like last weekend in Cologne:

"A keeper at a zoo in the western German city of Cologne has been mauled to death by a tiger.

Police say the animal wandered through a gate that had apparently not been shut properly. It reached an adjacent storage building, where it attacked and killed the 43-year-old woman.

The tiger was then shot dead by the director of the zoo through a skylight, before it could get to public areas.

Members of the public were ushered to safety, and the zoo was briefly closed.

It is not the first time this year animals have escaped from their enclosures in a German Zoo.

Last month five chimpanzees broke out of their pen in Hanover. In that case, however, they were recaptured before anyone was hurt."
