Hello Everyone, I am looking at trading for a German bass. It is a 5/8ths size, laminated, and dates to pre-WWII. The label reads: Produkiivgenossenschaft e.G.m.b.H. Der ehemallgen Schonbacher Musikinstrumentenarzeuger Made in Western Germany From what I can see... the label basically says it is from the that the Produk-Genossenschaft, formally of Schonbacker Musical Instrument Makers, made in Western Germany. Does anyone know anything about bass from this period and area??
