The retailer of this drilling was not an unknown gunmaker in the east, but Carl Leberecht (1848-1933) in Amberg, Bavaria, or his son Karl Leberecht jr. The gun was proofed at the Zella-Mehlis proofhouse, evidenced by the ledger number 511. Suhl never used such ledger numbers. So it was most likely made there, and not by one of the better known Suhl makers.The leberechts held patents for an automatic safety and a 1913 one for a barrel selector on a drilling. The C.Leberecht shop in Amberg existed u ntil a few years ago, when the last Leberecht was slain by a robber.
