A steam plant comprising a Stuart S50 mill engine couple to one of their 504 boilers, complete with water tank, hand pump and dynamo. Difficult to imagine a worse paint job for an engine in terms of colour and execution, the whole plot would look ten times better stripped and repainted into something a little less offensive (and you have to go a long way to beat the standard Stuart livery of dark green and black).
Base 20 x 10 inches
Handpump 1/2 inch bore
