guitarinsite.nl: Serial number: 90237138 Production year: 23 January 1997 (serial nr.: 138) (Manufactured Electric: Nashville or Memphis. Acoustic: Bozeman, Montana.) Note that part in parenthesis. My '67 SG Standard was dated correctly by guitarinsite even though records are notoriously sketchy/incomplete for this period. Even Gibson employees couldn't date it correctly until I told them where my serial was located in their own records. Numbers for some years were located in several different areas and out of order. Those records have since been replaced, so one more opportunity to screw them up. So why am I positive that the serial I got from guitarinsite.nl is correct? The headstock inlay, the wings, the shape of the pickguard, the tuners, the control cavity wiring, the bridge, the truss rod nut, the pot date codes, the date and serial on the card that came with the guitar when it was sold, and, oh yeah, the fact that I bought it in early '68. Not saying guitarinsite.nl is 100% correct, but every guitar that I've checked there was accurate (evidenced by original receipts, physical exams, records from dealer who sold them, etc).
