Not sure that the name for the encircled >>B.A.<< mechanic would be Bruno Apel of Suhl, but that is one of the few matches. A relative of the estranged GGCA founder Dietrich Apel. Brno A. or Bernhard A. but for now I don't know if either exists as a Z-M mechanic. Now there was a Brno Anschütz of Z-M but I am unsure if he was active in 1905?

Cheers,
