I have a beautiful violin shaped model here now made in 1910. Stamped in the back of the Peg box;
-----------------------
Lowendall's
Grand
Concert
---.---- (design there)
Stradivarius
-----------------------
This is a 7/8ths (or 4/4 size of its time), '
BERLIN' stamped in the upper back button. Beautiful reddish brown varnish (the red well faded), 41 7/8" string length with a grafted neck, original scroll and gears with slight scars from a previous mechanical C-Extension
. Wide lower bouts (28"), deep ribs (8 5/8") w/outer linings, slightly sloped shoulders and easy to play. Well arched round back tapered in the upper bout towards the neck, ribs are 6 1/4" wide at neck. Well flamed maple throughout with fine-medium grained spruce top. Deep warm tone with good projecting power.
This looks to be the real deal from its period, a professional orchestra bass. For more information on L. Lowendall and his son Louis Jr.,
read this article from the 1893 exhibit in Chicago.
