1 inch scale Allchin agricultural engine - stock code 9135

A finely made Allchin to Bill Hughes' "Royal Chester" design, scaled down to 1 inch to the foot from the original 1 1/2 inch drawings - never seen one before in this scale, we'd be interested to know if another exists.

Unsteamed from new, the engine runs on air - given its "ex works" condition we've made no attempt to steam it.

Pictured opposite in company with a "standard" 1 1/2 inch scale engine and a 2 inch version, again the only example we've seen in that scale.
