A 5 inch gauge "Britannia", put together from a kit in 1999 and unsteamed from new. It has been well put together, pushes along freely (which puts it in the top third of kit-build engines in our experience!) and has some nice detailed bits added including works and tender plates.
Complete with original manufacturer's assembly instructions and hydraulic certificate for the boiler.
Locomotive 50 inches
Tender 26 inches
