I have a 1966 335 from Gibson Custom Order, it is white with chrome pickup rings & chrome truss nut cover,it also has white -clear knobs similar to the gold-clear Les Paul knobs. it had some pro-repair done to the head stock back in 1974 by Toshi at Zenbu Guitar (Sacramento). The paint has yellowed a little over the years but it plays great with lightning fast action. The serial # has faded from the label, but the label says "union made" on it. All characteristics signify the year 1966. See the web site http://www.provide.net/~cfh/gibson.html#specs
To my knowledge there was only a few of these made.
I am currently taking offers on this guitar..Please serious inquirers only.
