I believe.
This set is a variation (a German variation) of the "Old Vienna & Coffeehouse Chess Sets" and the story is:
"The old Vienna or Coffeehouse style evolved from the earlier Biedermeier chessmen - probably influenced by the arrival of the Staunton style! These sturdy and serviceable chessmen - fairly easy to make for the numerous turnings shops in existence in those days - became the standard in Central Europe - the lands of the Austrian monarchy as well as Germany , Switzerland , and Northern Italy. major tournaments like Vienna 1898, Semmering 1927, and Karlsbad 1929 were played with these chess pieces."
Nimzowitsch in Carklsbad 29, with a similar set

The great maestro once played a game with these. That's right, one game. I worship, sue me.
A father of a prominent late Slovenian pianist Janez Lovše (1933 - 2012) was an avid chess player and as the story goes once played a game against Nimzowitsch (in a simul) and lost.
