Thanks its a useful link,The lorry with the chain drive looks likely to be the Daimler chain drive a common German army transport.
I've already made a basic Daimler lorry and an Ehrhardt armoured car,also an Austin series 3, These cover the basics. The Armstrong Whitworth I've been asked to make.Copplestones already has one along with the Russian Armoured car/Lorry (the name escapes me right now)hope this helps
