Castrol were pioneers in motor oil development. At the start of the 20th century with the automobile and aeroplane were rising in popularity, Charles Wakefield saw an opportunity to develop specific lubricants for these new engine types - the addition of Castor oil was the revolutionary element - making the oil thin enough to be effective when the engine was cold at start up and thick enough continue to be effective at high temperatures. From here Castrol was born. 

 

Known as the 'bow-tie' design, this early Castrol logo dates from the 1920s-30s when the company still used Wakefield's name. These early designs, using red, yellow and white are unusual enough, the addition of the Royal crest in the upper corner makes it rarer still. This example was produced by Bruton of Palmers Green, North London. 

 

For a fairly early piece of automobilia, this sign has survived the decades in decent order, both faces retain vibrant colours and a decent gloss. There are patches of enamel loss on both faces though nothing that impacts the legibility of the piece. The original flange remains present and functional albeit a little worse for wear. 

 

The sign measures 51cm wide x 41cm high and the flange is 4cm deep.
