Being in San Diego, I'd suggest contacting David Eichelbaum. If he'll take it on, pay him whatever he asks.

Alternatively, you could check with Dennis Berck in Oregon. That will involve shipping or a very long drive.

Either of these guys can build you a period correct bridge and use the right methods, including hide glue, for repairs. I try not to recommend people for vintage guitar repair based on reputation alone. I have seen work by both and it's top shelf. David made the bridge on my '36 000-18. The original was shaved down to near nothing, but since the footprint had not been disturbed he was able to create a perfect fit replacement. I don't own anything with Dennis' work, but I've seen it and it's equally good.

Summary - get the right repairman, forget the cost. Nothing is more expensive than cheap work on a prewar Martin.


EDIT: I think I paid $250 or thereabouts for the last BRW vintage replacement bridge I had made. That included the saddle and associated setup work.
