3 1/2 inch gauge part-built "Rob Roy"

An 0-6-0 tank engine to Martin Evans' " "Rob Roy" design. Work to date is pretty pedestrian, with some novel ideas such as one brass and one aluminium expansion link, grub screws fitted to secure the wheels to the axles and perspex valve chest covers. However, the commercially-produced silver-soldered copper boiler is a nice job, much of the chassis, cylinder and platework looks usable but the motion work is horrible.

Complete with the Evans book on building the engine.
