The labels and stamps in violin family instruments confounds most people. Some labels actually name the maker. Some labels credit a maker who was famous for making instruments with the shape and appointments after which an instrument is copied. Some labels are a 'trade name' made up by a shop for a particular model or group of models of instruments that share certain attributes. Some labels are outright fraud.
The label in this viola, JB, is a trade name for an importer who brought nicely made instruments to the United States in the early 1900s. We believe this viola to be from the 1920s. It's in great shape, sounds nice and is BIG!
