I was looking over this intriguing topic Gordon and was very surprised - how I did not reply and after all this time ... would like to now respond
Well, back in 1965 I was just a 2-year-old toddler and with a brief story - the firstborn of new-blood in the family ...
Sure you know the saying with new-blood, comes new blessings because in growing up was told stories of how life's situations changed for the better with my immediate family members - starting with my Grand-Mother on my Mother's side
That said - like you, got my first
Scalextric Set Christmas Day (1974) at 11 years, with two RWD Mini
Clubman Models ... one yellow, one red.
I never forgot the checkered markings on the rooftops of those 2 Minis while racing & how much excitement and thrills it caused because seemed like we raced for days (on-end) and straight into 1975
Anyway .. your second pic of the underside of green Mini is very technical looking (epically with the guide pin setup) compared to the Minis I had - remembered they weren't so hi-tech looking but a more compact motor style / setup that fitted on the inside of the chassis, which was then clipped on to Mini's body.
To help understand what I'm explaining with setup - here's a link ...

Some months later in 1971 (
probably for my 8th. birthday) got a Ford Escort (White) MK1 model

Same as you Gordon, wish I still had those Minis & Escort models today
