Gauge 1 LMS Royal Scot 4-6-0

A spirit-fired gauge 1 LMS "Royal Scot", this one has come to us as part of a small collection of gauge 1 engines in part exchange for a 5 inch gauge 9F (which seems to be going from one extreme to the other in size - it was certainly easier loading than unloading when we delivered!)

Assembled from a kit, the engine is complete and runs on air in both directions. The pump bracket is loose and fittings on the backhead are unfinished.

The boiler is stamped with its serial number, date and "Max WP 100psi" - on hydraulic test it appeared structurally sound, with various leaks from backhead fittings.

The unlined paintwork has been applied to a pedestrian standard. We would be inclined to strip it completely, repaint and carefully reassemble - given the underlying quality of the kit, there's the potential to make a decent engine of this.
