GE 810 in Michigan...
 

These sets were factory equipped with a 10FP4 CRT. Assuming it's got the original type tube and it still has decent emission, the 10FP4 is a brighter aluminized 10 inch CRT. The item # is 120705173422. Usual Disclaimer:
I have no interest or connection to this auction, just thought someone here might be interested.
