I would look for a music shop in your area that handles Violins, Cellos etc. Ask them for a good luthier. Stay away from guitar stores which may be a problem in Nashville. Or contact someone like Lyon and Heally.
INSIST UPON REFERENCES AND SEEING EXAMPLES OF THEIR WORK!
Repairing a concert harp is something that will take special skills. I work on far simple folk harps and experiment with different configurations.
Dawn, you raise a very good point. If sound integrity is not compromised and the instrument is structurally sound, I believe a crack might even lend some character and not be out of place on an instrument that old. I am concerned that they will take the instrument to a shop that will not appreciate the instrument for what it is and they will wind up with a total loss. While we know they could never sell it for it’s replacement value, it certainly would be that much to replace it.
The closest harp repairman to you is, fortunately, also one who specializes in antique harps and harps by less-well-known makers. His name is Howard Bryan and he’s in Lynchburg, Virginia. You can contact him through his website at http://www.hbryan.com. Let us know how it goes with your daughter’s harp!
I think you need to make a trip to Chicago with this one, if only to show it off. I never heard of a harp made by Wild. I think maybe he only signed it and didn’t make it? You might post pictures of it for us to see.
