Hi Mike.
I have had the truck blasted and have painted it portland stone(its still in bits). The cab does have a hatch in the roof also it looks like the chassis has been extended. Did the Aussies get the truck during the war or after? Also is there any record on how many are left today. Thankyou for your advice its great to share a hobbie that people enjoy, i will try and find the serial number on friday cheers Shane
