hi
The cliff barker van is a basic shell of a kit as supplied so you need to source the angle and any other detail bits. In short anything that is white in the pictures is not supplied in the kit. The body only kit is £55.00 I managed to source the dummy axle boxes and spring sets from GRS for around £20 plus postage. I was fortunate enough that i was given some wheels and axles of the right type by a friend so all that remains is the construction of a chassis with internal bearings, although not correct will allow me to build a 3 point compensation unit.
No I dont own a GRS van as a comparison.
Cliff does about 4-5 vans including the Bogie B sr parcels van, GWR Python and a few others. Best to call or email him and ask him.
