Sadly, without serial numbers, these will be a little harder than usual to track down.
1976 4-string Series I with Coco Bolo top and back.
Early 1980 4-string Distillate in Walnut.
Both were stolen in Reno, NV and have William Harris engraved on the inside of the electronics cavity.
Do contact us (http://www.alembicguitars.net/family/contact.html) immediately if you run across one of these in a pawn shop.
Pictures to follow as soon as they are available.
