[motto]

Here are a couple of close ups of the running gear. Original components were aquired and moulds made off them for production of the many parts that had to be made, some of them in large numbers.
One of the effects of this is the circular 'welds' in the first picture are all identical as they all came out of the same mould!
The 'solid' rubber tyres on the road wheels were foam rubber and could be indented with a finger tip.
