B&O P7 Class Locomotive 'President Washington' - H J Coventry

(Please note that this is ½" to the foot scale)

Constructional instructions and some sketches appeared in The Modelmaker (an American magazine) volumes 5, 6 and 7.

In 1928, Kennions made available a set of drawings (plans) and castings to build President Washington. None of these are available today. However, thanks to the generosity of member Bob Thomas, the Association has a copy of the Modelmaker articles and the plans. Because of their poor state, some plans have been redrawn and most of the prints are now available.
