No question that the earlier 53LC2 clock radio has much more eye appeal then the plain 54L1 that I posted above... This site says that
even the clock radio is often overlooked :

Note that the "inverted" speaker on this earlier set is a different design than the one used in the Westinghouse transistor portable and the 54L1, looks like the later design might have been cheaper to produce.
