Exactly. Mostly I'm just guessing. Trust the guy that wrote the bookYes, but he also had a 21-fret 4001 (full trim) Mapleglo, so look for the full-width triangle position markers.

Also look for the "potato-head" eight-string, one of two experimentals Rick produced (the other for John Entwistle).
Here's Chris with the 21 fret MapleGlo beside him:

See, I'm not so bad. I only have 3!
