Hi Guys I need help I have been asked to build one of these for a friend1/12th scale. On opening the box all sprues were still in their bags and sealed. However on opening the bags one part was missing, the seat and petrol tank assy.
Airfix no longer hold spares for this kit. Can anyone help.I will even consider scratch building the assembly if anyone can advise how. I am normally found on Aeroscale as an aircraft modeller. Any help would be greatly appreciated.

Regards

Den
