I have a Drilling (16-16 - 8x58 Sauer?) which does not fit this chart. It carries a date code of 2,07. I am unable to make out the proof house number for the year, but it is in the 6 hundreds. All barrels are marked Krupp & carry Nitro Proof marks, with loads given. The shotgun was proofed with or for Schultz powder. It is definitely a pre-1912 gun for the rifle barrel chambering is marked 172.28 - 59. Except for that 1 mm in length, all dimensions are a match for the 8x58 Sauer.
