The brown violin:
The usual attic-find German violin. Strad model. It probably hasn’t been played in 20 years at least. Agewise, these were sold in abundance during the 1920’s, although it could be 100+ years. List it as an antique. Fingerboard and nut are not made of ebony (bad). The purfling (inlay around the edge) is real (good). Maple in the back is plain with faked flame. Belly wood has reasonably close grain, which is good for the sound.
Your selling points are that (at least as far as I can see) it has NO CRACKS. Varnish is dry and it needs to be repegged; but other than that and a few add-ons (like new strings), this one will sing again.
It’s hard to value violins because people sometimes bid them too high. But I wouldn’t pay more than $100 as-is, or more than $250.00 fixed up. But you never know, could go much higher ….
How’s this to list:
Antique German Violin
Stradivari model, condition as shown, no chips, cracks, or breaks. Wear is commensurate with its age. Has a strong new bridge and the purfling is inlaid. Close-grained wood in the belly. Could use a new peg and strings to play again, polish and fingerboard dye to look its best.
Here’s your chance to own an antique violin, already aged and played in.
Comes shipped in a case for added protection, along with original bow.
(Make changes and price it, of course, as you see fit.)
