A Sivori Viola Bow With Hannings Certificate

A mid-century “Sivori” viola bow. Also stamped “France” behind the frog. Sold with a certificate from Lynn Hannings. I do believe these are German, with a range of possible attributions from Roth, to Reidl, and even Nurnberger. Needless to say, a good trade bow. Suitable for the advancing musician on a budget or as a professionals secondary bow. Nickel mounted. 69.5 grams, balanced.
