and a model called the "Performer" which was a pared down
Superadio (C Cells instead of D) which lived up to its billing.

Hmmm. I've had an SR 2 since about 1991, but I never heard of the Performer.
I'm interested ( I also have an old GE P780 which is my best MW DX radio of the
many radios I have). I just did a google and Ebay search but nothing turned up.
Can anyone elaborate on the Performer or direct me to a picture or a writeup.
Thanks.
