I think it should have a pretty high WAF considering it is a nice looking set.
Not only that, it features the KCS66 chassis which is a greater performer. Besides having a an excellent S/N cascode tuner and keyed AGC, it features a full 4MHz video bandwidth, has intercarrier sound and a DC coupled video amplifier. (Does this sound like RCA salestalk?)
RCA went to the DC coupled video amplifier I believe with the 8T241 KCS28 chassis. It dropped DC coupling with the KCS47 and went back to it with the KCS66. DC coupling generally means improved low frequency phase response which means the picture quality on this set should be excellent.
It is a great find!
