Wow, I'm pretty impressed if you've managed to identify most of this... clump of cars, I find it very difficult. I do see a few things, though:
quite a lot of old metal wheel Lesneys... problem with these is, that this is known is... that the condition of the body is not known! (in other words, we see the baseplate but not the body)
Corgi Ghia Mangusta with detachable body
Corgi Ford Zodiac motorway police
Corgi Land Rover(green), looks to be an early version
Corgi Land Rover (red) breakdown truck
several series 1 Models of Yeasteryear
Lesney Mighty Antar
an unidentified white or cream Dinky missing its door(s) on the left
Lesney Alvis Stalwart
Lesney Pontiac convertible 39b, yellow, missing windscreen
a big, white US car, possibly police and very likely Dinky
I've just been looking on a couple of similar lots tonight - it really is a 'needle in a haystack' project. Only takes a very few interesting items to make it all worthwhile, and sometimes, with huge lots, it's worth a gamble even if you can't spot the 'needle', simply beacause there's a high chance that 'something' interesting is present.
I decided against bidding on 'my' lots - the average age of the models was so, that I believe most models would be mid 70s or later, so tons of fantasy vehicles, and also I was unable to spot one single model I knew I'd like to have. I hope you find a few treasures in this lot, certainly tons of stuff to restore, so you won't get bored
