Unfortunately I haven't found any mention of the full name anywhere.
I can tell you the car was registered 32 EKR, which was a Kent issue from February 1959 (Folkestone is, of course, in Kent).
I can tell you the name of the lady in your puzzle car picture (Pamela Taylor) who was 23 when the picture was taken.
But other than that there seems to be nothing out there.
I'll have a guess at Taylor Electric Ltd., simply on the off-chance that there was a family connection with the girl in the photo - I think her father-in-law was Fred Taylor, who worked for an electrical company named Gilbert in Folkestone who did actually make some small electrical commercial vehicles.
If I'm wrong then you'll have to open it up.
