PART 1
Again please note these are my own musings based on observation and assumption. They need to be verified or disproved. They are presented as a springboard for discussion and further research.
So, as mentioned before I'd assumed for a long time that all ' Red' Greenies were the same and were the first 'model'. I use inverted commas because I don't really think we're talking about specific delineated models here but rather slightly different manifestations of the same model(s).
A couple of things happened that started the ball rolling. First, a comment in another thread that the early machines (1966) were 'slightly different'. Second, I'd been puzzled by the way the front of the chassis was formed by plate thus allowing the engine to drop down lower. Obviously the reason was to drop the engine and reduce the bonnet height, by why not start with a design based on straight rails that put the engine height where it was wanted without the need for this extra manufacturing step. Just struck me as odd. Then the penny dropped! Maybe he DID start with straight rails. A 2am trawl through my photo collection revealed something I'd missed. Some did have straight rails!
The second was discovering a machine that had the circular logo we see above. I'd not come across it before. Everything I'd seen had the word 'Greenfield' in a stylised diamond above the bonnet grille. Clearly this was an earlier logo
To be continued.......
