I estimate this picture was taken in the late 1960ís - very early 1970ís. On the 3-wheeled front the image clearly shows the Reliant Regal
3/35 & 3/30, Reliant Regal Supervan III and the Reliant Ant (TW9). Also, right at the back on the right hand side is a Reliant Pick up van. In case your wondering about the lorry, Reliant used to also make
fibreglass cabs for Ford Lorries.
