I think the red 74 superfast bus box could be quite rare.
Also the 53 mercedes but you need to photograph it outside in daylight without flash as I can't tell if it is dark red or maroon
we need to know what colour the base is on the 69 rolls royce
ditto the 20 taxi, has it got a silver plated or grey enamel base
and the combine harvester is rare if it does not have a circular hole in the base
The #70 Grit Spreader looks to have the uncommon cream coloured back rather than the standard primrose yellow shade.If your blue #31 Lincoln lacks the tow guide under the front bumper plenty of members here would be interested in buying it!
