I bought out the inventory of a violin shop in the Washington, DC area about 10 years ago. I have many, many violin, viola, cello, and some bass parts at very reasonable prices. Some of these parts are quite old and of high quality hard to find in today’s market.
I have lots of Ebony pegs new and used. Bow parts including frogs, ferrules, nuts, tensioning screws, and bone inserts. I have Ebony bass fingerboards and several roughed out Cello necks. Let me know what you need and I will send you pictures.
