But Luthier's Mercantile is a reputable outfit. The guys I deal with locally admit that theirs are just "ebony colored."

"Ebony" is a pretty generic term, less specific than it once was. It is possible that they have pegs from a related tree. I just hadn't seen them in local shops.

The "bone" flamenco pegs would have the right color, but don't seem to have much spare material to make a finger shape on. Or maybe I just don't have the right mental picture of what's intended.
