The Aga Model C or 47/10 Range Cooker (it cost £47 10s!) was made between 1936 and 1941. It looks similar to the much more numerous Aga 'Standards' range cookers that were introduced as its replacement but shares few parts inside.
Spare parts are not available as there are so few in operation that supporting them is not economic.
It was the first Aga range cooker not to include a boiler and has a smaller top oven than bottom. Easily identified by its vaguely triangular door that covers the air intake and super long door hinges.
It seems lots were exported to France after the war, presumably when French domestic production of similar items had yet to recover.
