There's quite a good side-on shot with clear view of the bogies here. The Tri-ang AL2 type are pretty close, I'd say, just 3mm short in the middle really. The big difference is where they tooled on the AL1 style bracket, top centre (which is actually attached to the body in real life).
The motor used in the two singles (LOTI & Caley) were the same as used in the TT Britannia and Merchant Navy. The motors in the 0-6-0s, Prairie and Castle were shorter.
The 1938 Brake Thirds needs two different sides, but those on the 1938 Thirds are the same both sides, though each 'compartment' section only has a door on one side (the middle one has none, so accessed via the, now removed, tip-up seats only).
Nice, but isn't that station building is really rather too wide for the platform, even with selective compression fo the 'six foot' rule? Perhaps a small (ornate?) canopy would suit better.
The fins on the estates didn't change but were always a little lower than those on the 1958 saloons, though not as reduced as those on the 1961 revised saloon models. Quite noticeable if you compare side on A55 Mk.2 saloon and Countryman (Riley & MG saloons didn't change but had a shared different style anyway).
As Jeremy says above, North British 0-6-0DH for Mauritius Railways. Basically an enlarged version of their industrial shunter. Similar 0-4-0DH locos were built for BR.
Lima did three cars for their car transporters: an H0 scale Mercedes 220 'Fintail', a 4mm scale Mk.1 Ford Capri and a 4mm scale Fiat 131 'Mirafiori'. The Sunbeam Alpine was in the Tri-ang MINIX range, later briefly revived for the Hornby Cartic-4 when the Triumph 2000 mould they'd been using on their Carflats wore out. The Hornby Sierra followed shortly after that, but definitely post 1984.
Spring to Summer 1985. First RM review in the November 1985 issue, 1956-8 Hillman Minx.
If to be used together I would keep in the 1:75 to 1:77 range.
Husky also did the Studebaker Wagonaire (sliding roof) station wagon (estate). Must be a similar size, though dogless!
Scale Link, John Day/Malvern Models, Transport Replicas, MiKits, Fleetline, Trux, Westward, Eames; though some of those ranges were already gone by 1984.
It was very sparse on the car/light van front if you wanted anything introduced post 1965.
