The recent 'big push' on the ground crew front included painting (at last!) this Airfix tractor and bomb trolleys. This came as part of the (hugely expensive) Stirling bomber kit - which is why hardly any of us have one! I was given most of the parts for this nearly ten years ago by a chap from whom, as a result of an eBay transaction, I was buying some parts for an old Volvo*. He had looked at my transaction history and gave me (free and gratis) a box of kits and parts!
I had enough parts to build the tractor (minus rear wheel arches and othe non-essentials) and two loaded bomb trolleys. Somewhere I have a third, albeit lacking bombs. Given its shaky start in life I think it doesn't look too bad.
