I wish.
Mine is a '65-ish (back plate labeled Fender Electrical Instruments pre-CBS takeover) silverface w/ Eminence (12820PA) square backs making it a later blackface internals amp w/ silverface/blue cover.
This mix makes it pretty easy to date w/o taking out the tubes to get to the serial.
I guess it is worth a bit more as it was a "transition" model that was only available for a year?
I do know that replacing my fragged cone Champ speaker w/ a Celestion retained that little cruncher's sound pretty well.
