Bill,
I know I mentioned getting another from Marko if he was up to building one, but I don't think I'd be interested in a vintage spec bridge (I'm pretty sure that's what you are going after here).
I'd like to find a 70s Starfire-II restoration project someday that is within my ability to repair/refinish, and one where I wouldn't feel as bad about routing it for the bridge. I have a 2-pc Alembic style bridge waiting, but I might consider doing one of these on the off chance that your machinist is building it up with the sustain block - like the one on my JS-II that Marko built. It would keep the options open.
