Hi BB,
Regarding the paint job, I had a choice between 2 hammer finish blue paints at the local Bunnings (White Knight paint) v Supa Cheap Autos (more of a brighter blue). I ended up going with the White Knight paint because the "Scott Bonnar Lawn King" decals I ordered off Ebay had the exact same coloured blue background. Neither the engine paint, or the chassis paint are exact replicas of the original paint colours, but were pretty good value (at about $20 per can).

Will keep you posted.
