The collection continues! Here’s a Vintage BEAVER BRAND DOUBLE SIDED CONCERT TREMOLO KEY F/C in great condition! Made in Germany around 1924 it Has wear from being almost 100 years old but no missing parts as far as we can see and we tested it for sound and it sounded great to us but just a reminder we are selling this as a collectors piece not as a playable instrument due to its age. Any questions just ask!
