This is one of three 4mm scale ex- LNER O2/2's constructed primarily from my own design of nickel silver etch for the chassis and some parts of the bodywork.
Scratchbuilding is also combined with these etches where an etched part was unnecessary. The first of the three had most of it's fittings hand made, whereas the subsequent two had full sets of patterns made and castings supplied for all the small details
The wheels are by Exactoscale and were released in 2010. The pair of engines started in November 2011, use an increased number of etches from my own designs for the tender and superstructure.
