I think Eiji has solved your problem. The card for 86 was filed away in correctly, but I managed to find it today! From looking at all the images I have of this bass, and with Eiji's impeccable record keeping, we all know know this bass' true identity. Here's the SCANT details from the file:
serial number: 74-86
top: Maple (Western)
body: Mahogany
back: Maple (Western)
neck: 5-piece Walnut and Maple
scale: 30.75 short
peghead veneers: Flame Mahogany (sample)
controls: PF6
There is an undated note of a new owner in Virginia, and now I can add you.
Hi number 86! So glad we know your name now!
