Dear Mr. Jamison, Badisches Landesmuseum is not in Karlsruhe, but in
the castle "Schloss Bruchsal", D-76646 Bruchsal. I don't know the
museum in Gera.
Interesting to know:
Franz Oehrlein Organs and Automates maker, Mainzstr. 33, D-55129
Mainz(?) is very specialized with mechanisms.
Gottard Arnold makes lately little figures like the original ones on
the front of the black-forest clocks. He is a very high specialist.
Address: Fachstaettehist. Musikautomaten, D-76669 Bad-Schoenborn.
Best regards from Mirecourt in France.
