No, not sourced from BEMESU or Sauer as it passed thru the Zella-Mehlis proof facility in late 1929. Interesting ledger stamp of a fraction though? Looks like the tubes were worked after it was originally finished.

Although the longarm wears the name of Büchsenmacher Adrian Kowalski in Ahorn, I do not find him in any period listings. However, I do see that he is currently active. Maybe he performed some task on it in recent times.

I don't know if the engraver was a temperance man or not, but Suhl engraver & historian Henrik Frühauf might be able to identify the engraver.
