M C Olley - past resident?

I found this black and white picture on Ebay. The only information provided with it is this:

Ford D Series Tanker, M C Olley Transport Ltd, Fairseat & Rainham

I guess this was taken some time in the '60's, if I were an expert on number plates maybe I could pin it down a bit more.

Perhaps M C Olley was a resident of Fairseat back then?
