retriever:

Here is my contribution at to how it was. This is from the Roger Kenney archive. The Thames Trader boxvan carries Atlas Lighting signage whilst the subject itself is a Davis Bros Leyland.
Amazingly BMC were still manufacturing the very dated A60 in 1969. I know the shape of the British sportcar appearing from the left but just cannot remember at present, maybe someone will recognise the type.
Sorry about the scratches. Have not had time to ‘photoshop’ them out.
The sportscar may not be a production model - I’ve looked through A TO Z OF CARS 1945 -1970,by Michael.
Sedgwick and Mark Gillies - and I cannot find that particular model. Therefore,it could be either one of
those kit cars that were commercially available,or a homemade special built up from existing components,based on say a Ford motorcar chassis or whatever.
Strangely,nobody has commented on the magnificent lorry in the second photograph of this thread 
But I will

AEC Mammoth Major Eight Mk III Flat/Container-bodied 8x2 or 8x4 Lorry,TGJ 529,1957 London registered
and originally was probably a Shell Mex British Petroleum tanker lorry:-

I understand the logic behind a Chinese six rigid but what was the reason for this one?

Twin Steer Chinese Six Tractive Units.
The reason for the Foden S34 Sabrina DAE6/32 6x2 Twin Steer Chinese Six Tractive Unit,
FLG 497F, James Hemphill,Polmadie,Glasgow,Scotland.No.187,and other marques of twin steer tractive units goes back to August 1964 when the new Constructon and Use Regulations came in to force.These allowed 32 ton maximum weight articulated lorries to run on five axles,either two axle tractive units with three axle semi trailers (2 + 3),or three axle tractive units with two axle semi trailers (3 + 2).

Although both Atkinson and ERF produced chinese six twin steer tractive units under the 1964 C & U
regulations,they also produced twin steer tractive units that had front and pusher steer,i.e. the second
steering axle was positioned immediately in front of the driving axle,as on this magnificent lorry:-
Atkinson Silver Knight TRS3266RR,Mk 1 Panoramic-cabbed, 6x2 Front and Pusher Steer Tractive Unit-Flat-bodied Articulated Lorry,KWS 666F,UNTOUCHABLE,of 1968,powered by a Rolls-Royce Eagle 220 Diesel Engine,and operated by Pollock (Musselburgh) Ltd,Scotland,fleet No.9.The driver is Wullie Grandison:-

In 1972 the law was changed to allow 32 ton gross train weight articulated lorries to run on four axles.
History repeated itself in 1983 when the Construction and Use Regulations allowed artics to run at 38 tonnes GTW on five axles using 3 + 2 or 2 + 3 articulated lorry combinations,but operaters had a greater choice of three axle tractive unit axle configurations:6x2 front and pusher steer (twin steer),6x2 pusher axle,6x2 trailing (tag) axle and 6x4 double drive. And Scania later came out with the 6x2 twin steer with lift up second steering axle,and also the 6x2 front and rear steer tractive unit in that the rearmost axle steered.
Twin steer tractive units and twin steer rigid lorries are the best road holders!
