3 1/2 inch gauge North British 2-8-4T

We sold this one back in 2015, it's recently come back in pretty much the same condition, as part of the owner's "workshop declutter" project. Pictures opposite taken last week, words below from the last time it was in.

An unusual model of a North British 2-8-4T, built for the Ferrocarril de Antofagasta a Bolivia (Chilean & Bolivian Railway to you and me) - originally a 2' 6" gauge line, later converted to meter gauge.

This is a well advanced project from a prolific engineer - we had seven engines come in from him recently. The pictures show it loosely assembled, work to date comprises a largely complete chassis, much platework and a silver soldered copper boiler complete with combustion chamber and a pair of serious-looking thermic syphons.
