In 1899, Merryweather produced the world's first successful self-propelled steam fire engine, the 'Fire King'; the first was dispatched to Port Louis on Mauritius. The first motorised fire engine in London was a Merryweather appliance delivered to the Finchley Fire Brigade in 1904. It was commemorated in April 1974 by the issue of a 3.5 pence Royal Mail postage stamp. The actual vehicle is preserved in the reserve collection of the Science Museum at Wroughton in Wiltshire. Another notable survivor is the UK's oldest known aerodrome fire/crash tender, a 1937 Merryweather with a Commer engine and chassis, now preserved in running order at Brooklands Museum in Surrey.
