Devonshire / 5HP Road Locomotive Boiler information

There are two sets of boiler drawings, one for the DCC engine and the other for the SCC engine. The two sets of drawings are identical other than the postion of the injector clack, the position of the hand hole in the top of the boiler barrell, and the DCC boiler has an adition bush for steam feed to the manifold.

The Devonshire boiler barell is 13 " in diameter by .375 " thick wall. The boiler has a flanged back head and a flanged throat plate, making it much closer to full size practice and greatly improving the appearance of the boiler.

Boilers are not available directly from Little Samson Models.
