Not what I expected but if the initials are "RL" it may point to a Zella-Mehlis origin by R. Langenhan. The time periods seem to overlap. Odd though is the date code with the ledger number while the Nitro stamp & location isn't typical of the Zella-Mehlis proofhouse. A maker in Zella-Mehlis would not have sent his weapon for proof in Suhl. We might assume that some Suhl maker with a A&D boxlock with lower scears, sideclips and sideframe reinforcement employed "RL" as a tube knitter. Max Möller was one such Zella-Mehlis craftsman who was sourced by Suhl makers for his talents.
