AHM's 1977 price list includes the 4-6-4 Hudson J3a with a retail of $89.98. By 1980, this NYC Hudson model was in AHM's catalog at $198.98.  AHM's 1981 catalog features both the Boxpok and Scullin Disc Drivers variations. The Scullin example is noted as NEW in 1981.

Plans for the New York Central 4-6-4 Hudson were presented in the November 1960 issue of Model Railroader.
