Help with cartravision

[bgadow]

The 528 in the model number tells who built it-Warwick. I think Sears was their only customer. Later Sanyo took them over. The 312 on the crt means it was made by Sylvania; they sold to many other companies. Just as a TV, if it didn't have the catrivision, it would not be valuable but would be kinda rare...not many have survived. As a combo, a real keeper!
