Released in March 2010 this is one of a pair of wagons, based on models seen in Hunts of Marlow - a ironmongers shop in the Buckinghamshire town. The shop also sell some model railway items.
This particular model was in a reddish-brown colour and the running numbers were the sixties - ie from "60" to "69". See item 87b for the grey wagons. Hence it will be possible to collect twenty wagons - ten of these red plus ten of the grey ones!
