Geoff,
On the WW2 Model makers site you can buy rope and anything else you want to tart it up with, loads of jeeps on their in all guises.
Great project, normally kept for long stays in hospital though. I built a sherman and a spitfire when I was in many years ago. Keeps the mind applied!!
Incidently, a WW2 Ford Jeep from 1943 with provenance of DDAY sold for £23,300 at the HH Auctions at Duxford in December...............like good rifles the price can only go up!!
Happy New Year mate

1943 Ford GPW Jeep - Price Estimate: £30000 - £40000
