Serialized Sauer tubeset from 1923 and passed thru Suhl Proof facility in 1924, even with the ledger #, Suhl used a ledger number for about 6 moths or sent their wares to the Zella - Mehlis Proof Facility during renovation, but I believe it was in 1921/1922? Repair in 1938 but I know not why Francotte whaled on it with his hammer unless the custodian wanted Francotte Chokes?


Those are barrel extension you note.
