Selling ebony fingerboards from a luthier’s collection in New York. These are believed to have belonged to luthier Carlo Greco, but I can’t confirm that. What I can confirm are that all four of the boards are the same dimensions and scale. Each fingerboard is slotted with a 10” radius, 24-3/4” scale, measures about 1-5/8” at the top, and about 2-3/4” at the bottom.
