Here are my Triumph 1800s. The dark blue with blue hubs is a variant I didn't see in Chris's list.
Looking at my two-tone Minxes and and Oxfords, these also have variations in the masking around the rear:

The left-hand Oxford has treaded tyres, so is later than the right-hand one (assuming both are still on their original tyres of course).
I only have one taxi, but looking at pictures online, some have the green going further back than others. My example has a 40H baseplate, showing that these were still in use a couple of years after renumbering.
The plastic Brimtoy Morris Minor sits quite nicely alongside the Dinky Oxfords. It should be a touch smaller to match the Oxford's scale. This Minor originally had a plated finish, but when I bought it, there was so little plating left that I removed the remnants to make it more presentable. The plastic enables the quarterlights to be modelled. Dinky, understandably, haven't included these, but interestingly they have modelled the slightly raised bases where the quarterlights went.
It has been great fun getting these models out of the cabinet and studying them. I even discovered a spare cream and green Oxford I hadn't realised I had, thanks to this thread!
Regarding Idris's question to Chris about books, Mike and Sue Richardson's book "Dinky Toys and Modelled Miniatures" is a great book which first inspired me to take more interest in Dinky Toys. The section on pre-war toys is the best part, as they seem to lose a little interest when it comes to the later models. The Great Book of Dinky was a disappointment to me, as it's just an illustrated listing with no interesting text to go with it. No book can deal in-depth enough to compete with the experience gained by collecting the toys and talking to other collectors. Magazines such as Model Collector and Diecast Collector sometimes include some good detailed articles. The early issues of Model Collector had a great series of Dinky articles. I'll be interested to know what Chris thinks on this subject (and sorry for sticking my nose in!
