Krupp Double Set
ŠPaul M. Alvarez 2003
A customer recently sent me these photos of this most unusual Double Barrel Shotgun/Rifle set. This gorgeous sidelock action was made by Fried Krupp in Essen, Germany in 1950. It has four sets of barrels, three shotgun and one rifle, and a claw-mount scope. The stock has extensive ivory inlays and the receiver is exquisitely engraved.

The shotgun barrels are in 12, 16, and 20 gauge and have 2-3/4" chambers (70mm) so it is useable with current production ammunition. Many of the older Drillings, in particular the pre-war guns, were chambered for European shotshells that were somewhat shorter than their American counterparts, typically 2-1/2" or 2-9/16". This was done in an effort to reduce recoil
Unfortunately, full length shells can be chambered and fired in these guns. This results in increased pressures and recoil, and blown patterns. Always use the correct ammo for your gun and have it checked by a competent gunsmith before firing.
The rifle barrel appears to be in an unusual caliber. It is marked 7.8X53. I have, as of yet, not been able to find any information or references to this cartridge so can only take a guess at the ballistics. One can only speculate as to why someone would have chosen this particular cartridge over the 8X57R or 8X65R
