Interestingly, it has a serial number.

My '76 Series I guitar has the serial number on top of the headstock.  I'm not 100% sure, and I'm not at home at the moment, so I can't check, but I believe my '77 Series I 12 string also has the serial number on top.  This one sure looks like the real thing. 'Tis a puzzlement?
 
Bill, tgo

I know the seller--he's a straight up guy. Worked at both Alembic and Stars Guitars back in the day. Proceed with confidence...
