Part-built 3 1/2 inch gauge Stirling Single

A part-built 3 1/2 inch gauge Stirling eight foot single, the work of at least two builders and something of a curate's egg.

Chassis is decently made, it turns over freely and runs well on air.

Boiler and platework are pedestrian - standard of construction and amount of silver solder used on the boiler suggests hallmarking might be more appropriate than pressure testing.

Complete with drawings.
