This is a fruit van marked with the letters "G" "W" but also marked "FRUIT" and "Return empty to Evesham".
It is a bauxite van with yellow lettering. The details for this van came from a photograph in a book about railways in a section entitled "Heavy Freight and Fast Freight".
Each one was meant to be marked with a running number in the "2351" to "2359" series. However due to an oversight by both Dapol and myself, they have all been printed bearing the number 2356 - which was shown on the original photograph I was using.
