65b Jaguar 3.4 Litre, issued 1962, length 68mm, box types C-D and E.
65c Claas Combine Harvester, issued 1967, length 76mm, box types E and F.

65a model.

The one on the left has the Silver number plate.

The Metalic Blue models, one with domed crimped axles the other has domed riveted axles.

The 1st issue the Metalic Red model.

What a difference half a mm makes 9x20 and 9.5x20 treads.

So many shades of Red, the Red one on the bottom left seems to have got a Metalic Red bonnet fitted in error.

The 65c model.

Two real colours of Red.
