6" scale Compound Steam Tractor The half size Burrell Gold Medal Tractor makes an excellent stable mate for the half size Little Samson.  The increased complexity makes it suitable for the experienced builder, or those with a little more time. The Burrell Gold Medal is a charming model, the proportions of Burrell engines being widely accepted as amongst the best engines built. The model is a compound, has three speeds, and is sprung on the front and back axles.  The third speed gives it a fine turn of speed where the road conditions allow (tarmac and good visibility).  Rim brakes are fitted. The vast majority of full size Gold Medal Tractors were fitted with two injectors.  However the intention is to fit a mechanical pump, which happily is geared down for superior performance and quieter operation.  Works drawings for the mechanical pump are one of very few I do not have, but are I believe available from the Museum of English Rural Life; least ways I have the drawings numbers and they refer to the GM pump. Presently the cylinder is in two halves, split just below the top, you can see the line in some of the pictures. The plan is to revert to a single casting and to core in all the steam ways. Discussions with the foundry already fairly advanced. An aluminium cylinder will then be cast to proove the revised pattern and bandsawed up to see exactly what is going on. Pictures on this site once it has happenned.   Overall length of model:  7' 0" Overall width of model: 2' 11" Overall hieght: 4' 11" Weight: 16cwt More on this page to follow.
