Mystery Gerald Titus dulcimer 1967, odd fine-tuners
Instruments- discuss specific features, luthiers, instrument problems & questions
Virginia dulcimer maker Keith Young used to make flat-bottomed fine tuning wooden beads similar way, with a hole to thread the string through. See the various photos in this thread.
Keith's dulcimers look very different than yours though in all other ways. I don't think Keith invented such things either, I'm pretty sure fine tuning beads that slide have been used on other instruments besides dulcimers.
I'm wondering the purpose of that deep slot. Do you think it might held an original wooden bridge? I've seen lots of dulcimers with their bridge inserted into such a slot. Even the Keith young in the above thread has its bridge set into a cut slot, though not as large as your slot.
Sorry I have not heard of this person Titus. Maybe someone else has.
You might ask @patricia-delich who is very knowledgeable about 1960s-70s California dulcimer people and who publishes "Hearts of the Dulcimer"- see her page here: https://fotmd.com/patricia-delich
(btw i removed your other thread that was identical to this one, only one is needed)
