An A series ERF in the workshop. The only company I can think this may have belonged to was Chichester Grain, who employed an Ex Robert Baillie driver. (this is well before the CB radio craze and they all had two way radios to contact the combine harvester, hence the twin ariels)
The Ex Robert Ballie Driver was Brian Forster, who indeed did drive this ERF. After that Chichester Grain brought a Atkinson from Ballie’s (POA 509M)
