And this fine example solves something for me as I've seen many Suhl examples wearing date stamps with ledger numbers from September 1923 till say March-April 1924 that Suhl did indeed employ a ledger number system. So for all those naysayers, hold your hand high & be counted as I dare, actually double dog dare you, to find say 1/2 dozen Suhl examples from September 1923 till March 1924 that does not wear a ledger number and prove otherwise. I wait cocked & loaded.
Charles Daly not S,D&G did not directly sourced the mechanics in Z-M.
