In Sydney Moir’s 24 Inches Apart he has a drawing of a Tool and bunk Van , I would say this was converted from one of the old original CGR Freight Vans. He has mention that this Van ran as part of the Avontuur’s Break Down Train which consisted of this Van, a coach converted to an Office & Sleeping Coach and an open wagon with one half built up as a Van. I have built a scratch built model of this in 7mm. I used plastic card and Mac Donald’s coffee stirrers. The Fox Bogies use resin castings from Bruce Green.
