Tomorrow I will go back with my Skeet's bore gauge to measure bore diameter. I will verify chamber length as well. But my Manson wall thickness gauge is permanently mounted on the wall. Any other pics that might help anyone?

Thank you all so much for your help.
This is why I read this bbs.

Typed 4/19 - 9:45amCST :
The drilling shotgun bores are 16, not 12. He had it listed as 12.
Right bore - 2 9/16 chamber; .680 bore; 2" of choke taper and .643 at muzzle.
Left bore - 2 9/16 chamber; .682 bore; 2" of choke taper and .645 at muzzle.
BBL length - 23 1/2" or 60cm
It is engraved Krieghoff Trumpf (if I spelled it correctly) under the receiver ahead of trigger guard.
