Yup, that's the Sterkens car. Took ages to find the pictures to make those decals !!!
The Arnesson car was based on the SWB Revell car:
As for the 6R4, I've made 2. The first is based on the MSC car:
and a heavilly modified Scalex Metro (every panel except the roof was modified):
How about this for retro?
