I also had an email conversation with him, but hate the old, you tell me what you think it's worth to you thing, so I dropped it. I can tell you I am in the middle of restoring a series one fretless and I had a very hard time finding parts and original electronics for it. New electronics are expensive, too. However, it will be cool when you are done with it. Alembic can still cast new pickups in the old molds. Also, Bartolini might make drop in pickups and electronics that might work well and still look good.
Good luck,
Dave
