Found a 1942 listing of the 45 MHz band FM stations that seems to support the assertion that double digit number in the call sign indicated the last 2 numbers of the frequency, with the leading "4" being assumed. W47NY did indeed transmit on 44.7 MHz.
There are some "oddball" call signs in the list that did not follow that convention, but these were like W2X (experimental - zone W2 signs) and other zone experimental signs, as well as some "normal looking" four letter signs.

The use of the last one or two characters in the call sign to indicate the city was apparent, as well, although I don't understand how "MM" was chosen to represent Winston-Salem. (W41MM, Winston-Salem).
