Are you looking for the one with the 660 casting number???
If so, casting number on the neck or base??? Crash

Crash, the above nbr was on the base. There was no nbr on the neck.

Sometimes you look far and wide and the answer is right next to you. I checked with a friend in the valley and he has one. Thanks to those who responded.
