5-string Persuader and 4-string Spoiler. Not 100% sure of the Spoiler serial (especially the 2) as the stamping is pretty shallow.  
All info appreciated. Thx

Sorry, these are both mine bought in the last few months. The Persuader is beautiful, the Spoiler is seriously beaten up.

Hi Nigel,
 
Please take a moment and write the serial number of these basses in the control cavity for future reference.  
 
Here's what I found in the files:
83S2903
top: Quilted Maple
body: Mahogany
through body neck: 3-piece Maple, 32 medium scale
fingerboard: Ebony with pearloid inlays
birthday: October 11, 1983
originally made for: Akron Music
 
 
88P4783
top: Walnut
body: Mahogany
through body neck: Maple, 32 medium scale
fingerboard: Ebony with pearloid oval inalys
birthday: February 12, 1988
originally made for: Manny's Music
 
Neither instrument had previously registered owners.

Wow! I forgot I found 2 files for the Persuader. The second (temporary and now destroyed) file had a previous owner in 2004 from New York.

Thanks Mica. If you want to update the Persuader file, the neck is actually a 7-piece maple/purpleheart laminate.
