Intherited from my great grandfather Emmett Culligan (yes, the founder of Culligan water), this is now an octave fiddle. The strings are 2X normal diameter, so the same tension produces a note one octave below standard violin pitch. The label reads "No. 1080; 20th Century Stradivarius Violin; (Patented Aug. 25 1908)"
The following information comes from The Violin Makers of the United States by Thomas James Wenberg. " Ulbrich-Tatter Violins. Operated in the United States. Original model with Guarneri-style f-holes. Top is made of many pieces of wood. Exaggerated bass bar, also used varius multiple bass bar configurations. Somewhat opaque, deep red varnish, highly crackeled. Received a patent on August 25, 1908."
Thanks to Peter Seman of Seman Violins in Chicago for the information.
