My Dad bought a new Trader in 1958,reg 487 BKA. a good wagon in its class.
I bought one in 1968? from Holt Lane Transport in Prescot / St Helens area, It was a C reg 1965 model ,ran it as a flat for a year then converted it to a tipper, had it on for Norwest Sand in Liverpool.
Any Thames Trader buffs out there?
