I wouldn't bet on the B.B dial guys going in that direction, since they seem to be fixated on the latter sets because of the dial and the fact one was used as a TV show prop. That's part of why they ignore RCA and Philco sets from the 1936-38 era, the dials are smaller and the appearance isn't flashy. There is no rhyme or reason for what is collectable and what is not, sometimes the only reason people want something is because they think everyone else does.
