An 0 Gauge Live Steam gas-fired 0-4-0 Tank Locomotive by Roger Marsh, built to the 'Ogwen' design, with gas burner and tank, twin cylinders with outside motion and under-mounted regulator valve with lever from footplate, with pressure gauge, water level 'porthole' and gas regulator to cab, repainted rather heavily in bright red, overall F-G, paintwork poor, both return links to valve gear loose, other minor damages, appears well-used
