NWL : Well you got me there...my version of the Greenberg Prewar Flyer book (1987 ) has no B or C versions of these cars listed, just the green roof ones in a 3 line entry. So maybe someone has updated the data in a later version. Anyway given their low cost at the time of manufacture I would expect them to be fairly common.
I have not looked at the 1987 edition in years. The guide was updated in the late 90s (I think in 1997), with that version having a blue cover showing a 1096 engine.
