The Drilling of which you are a custodian passed thru the Suhl Proof Facility in January 1924, almost 102 years ago, and was 42 for that month under the name of Emil Eckoldt . It was a period when either Suhl was using a proof ledger, or Suhl was sending their wares to the Zella - Mehlis Proof Facilty because their was a renovation @ the Suhl Proof Facility. It was proofed w/ a 15 Copper Jacketed Bullet. Just about any lead Cast Bullet for 9,3X72R will fit the bill.
Carl Lobbenberg was just the firearms merchant where he had a client & placed an order w/ Emil Eckoldt.
