Moe Foster did some articles in the 90s Bassist magazine, as far as I can remember his Jazz bass looked fairly conventional. He did say the ebony fingerboard had come from a double bass, but presumably it had had been cut down to normal Jazz bass proportions.
edit; OK, in the link it looks to have a somewhat extended fingerboard, but not so much that it only had room for one pickup, maybe 2 octaves or so?
