Hi Nathan,
Here's what I found out about 90K6247 from the instrument file:
top: Flame Maple
accent: Walnut pinstripe
body: Maple
neck: Maple, 34 long scale
fingerboard: Ebony, no inlays
pickups: MXY
controls: volume, pan, filter, mono output
birthday: not recorded, but likely early December 1990 (rub out was recorded on November 27th)
originally made for: Swee Lee, Singapore
If you've got this bass now, it's been a real world traveller!
