Sue bought this booklet called Fifteen Shillings Change at the railway exhibition last week and packed it as a Fathers Day present for me, which I opened this morning. It is a reproduction of a sales leaflet published by Kerr Stuart for their range of geared engines, 30hp, 60hp and 90hp. I already have a lot of illustrations and details of this family of engines and have every intention of building one to my 1:27.7 scale. I have already modelled the 30hp and 90hp models in 7mm = 1 foot. See this post for details.
The leaflet has been reproduced in partnership with the Hunslet Engine Company and the Industrial Railway Society. And the plan is that other historical leaflets will be reproduced in the future.
