I don't think Westinghouse had very many dealers carrying their TV sets back then. Even Westinghouse B&W sets seem to be scarce. I used to look at new TVs in the stores frequently in the late 50s. The only color sets I saw then were RCA and Silvertone. Frequently seen B&W sets were RCA, GE, Zenith, Motorola, Philco, Magnavox, and Silvertone.
