George... The pups (one died during a "mod" - the other is around, somewhere) were/are Peter Cook Customs, gold plated, like the rest of the hardware, and the only other time I have ever seen them were in John Entwistles basses made for him by Peter Cook, the one that sold for $30,000+, red/yellow vaguely jagged paddle shape, is one - it is on one site but can't get link at present, slow site... vaguely like chrome T'bird pups, but with 4 adjustable poles... I did not think that much of them, which was why they were outed...
That "was" his site, but his partner bought him out years ago - he has long since disappeared off the radar...
I've had her since the 70's and was told she was built around '72, but that may be wrong...?
I know he definitely made 2 6/12 double neck Firebirds but his instruments are so scarce, I have only ever seen one other live and never seen another bass, other than Entwistles...
