That's very similar to the profiles on the P.O. wagon info sheets. I think there may have been a drawing in Modern Railways when they were new, but whether that actually had much more detail Ican't recall (and I'm not sure where that particular issue is). It did appear on the Procor Profiles advert posters.

The vast majority of steam locos are like that. If the cladding didn't have a join they would only be able to slide it on from one end! Up the top is the best place to put it: relatively easy to get to when maintenance it needed but also happens to be where it won't easily be seen.

Whilst not quite a match for your 2nd era I did a survey of cars for 1972 looking through a large number of photographs of that date and trying to identify the type and age of vehicles. Where registration plates were not visible a middle of production date was chosen, unless there was some identifying feature that would help fix a closer date. The age profile was interesting: It certainly showed how rust-prone cars were in those days! Significant because there was an M.O.T. test to pass and most* cars of this period were unitary (most mass market British cars were unitary by the mid'50s, much earlier in some cases). For your 1965-68 period I'd suggest you renumber the years of the profile back by about 8 years (taking 1972 to be 1967, etc.). As a general rule if a model had been discontinued for more than 15 years spares would become increasingly hard to find, especially if it was less popular when it was available. * not all, the Triumph Herald being the most obvious exception.

I think I've found a Toplight Brake Composite that could fit that image, having a toilet style window each end: Diagram E82

I was thinking it should be, but what's visible of the arrangement of doors, hinges and toilet windows is a little indistinct with no obvious sign of a luggage area, hence the caution.

Top photo E148 Brake Composite and C70 Third. Bottom photo C73 Third and, I think, a 57' Toplight Brake(?) Composite though there were several diagrams of these. By this time it may if it had panelling originally (and not all Toplights did) then some or all may have been removced or been plated over.

Probably the Airfix version with plastic con-rods if the plastic underneath is yellow. If it's grey then Dapol.

Yes. It was Ken Stubley who ran The Engine Shed, Leytonstone who arranged the addition of those two designs.

Those are both the same type of Fiat 500, but from different angles. The close up emphasises the lower width. The new one is quite different with the bonnet opening cutting through at headlight height. Th red line on the doubled-up picture outlines the bonnet opening, nothing more.

I see it correctly has different numbers on opposite cab sides in that livery, 502 and 103. That might confuse some people.

According to this*, the station was completed in the Summer of 1957, so about the time the magazine came out. Of course, it doesn't guarantee accuracy, but unless someone comes up with a contemporary colour photo it may be the best option. *scroll down about 70% of the way.

There was a colour illustration of Banbury on the cover of Transport Age magazine, though it is a painting, not a photo. In the colour film 'Let's go to Birmingham' the Blue Pullman does go through Banbury (quickly) at 3:07 to 3:08, but there is a little more footage here between 5:02 and 5:04.

True there are minor differences (the axle mounted discs may have something to do with the smaller diameter wheels) but the basic arrangment of the distributors, load sensors, frame and brake levers arrangement is the same. With this, some photos and a G.A. drawing of the OAA it should be possible to work out how to upgrade the Hornby model. There is also a good OAA drawing in "An Illustrated History of BR Wagons" (OPC) though this can still help supplement because of the plan view.

The Rover 3500 was a Buick engine, but Buick replaced the design with a thin-walled iron design, so they were willing to sell the design and tooling of the aluminium one to Rover. Incidentally I did a 4mm Torana HB kit some years back (1990s).

The Valiants from Australia sold in the UK in the late '60s were the later VC series.
