Osborne prototype's Seymour Duncan PAF pickup. Note the serial number.

Osborne prototype's Seymour Duncan PAF pickup, as produced in about 1981, which is when I had the originals replaced with the SDs. The original pickups were Bartolini High-As that produced way too much highs and not enough mids and lows.

 

Note the 00006 just below the 22nd fret. Of the fifteen prototypes made, this one is serial number 6.
