Never thought about it before, but I think radical surgery to replace a headstock probably required a new fretboard, etc as well. Once involved in that, it'd have been surprising if the new board didn't have Alembic-style inlays. On the scale issue, I think it's a sign of the times: Though Fenders were, as now, the dominant standard for bass, there were a lot more short scale basses in prominent use by headliners. At least it was always my impression that EB-3s, EB-2s, Starfires, even Hofners and Mustangs, plus a host of other shorties were more common than short scales are today. Maybe I'm wrong about that. What do the other greybeards out there think?
