Might be someone out there who has a spare copy of the Commercial Motor 25th May 1920. An article in the journal has a write up about the Bath and West Show. Our Ruston is mentioned as it was displayed on Ruston and Hornsby's stand at the B&W show.
This is from the Commercial Motor Archives:-

Also looking for a catalogue from the show as the Ruston is also listed here.
Any help appreciated.
Many thanks
