E(Erdmann) S(chmidt) & HA(bermann), Suhl. The firm was founded in 1886 and I think both fellas were up in years. E. Schmidt I think to be a businessman and possible a Senator at some point. As usual with a business name, the money man was 1st and the workhorse/craftsman was 2nd. By the time this example was made Richard, Franz & Paul Stadelmann were the owners and possibly by 1927 Richard was out of the picture. What relationship they had to Schmidt or Habermann, I can't say for now.
Kind Regards,
Raimey
