This set of castings is one of the most complete ever put on the market,
embracing many feature not usually found on a model. For instance the
Condensor is cast integral with the rear columns, the controls are brought
to a platform in front of the engine and the Air Feed and Bilge pumps are
driven of the L.P. crosshead as in real practice. Also to suit the builder with
limited workshop facilities, large sections have been avoided as far as
possible.
