London Transport
1949
AEC Regent III RT
Saunders RT3/3
I have dated this bus by its registration and as KLB started being used in July 1949 so I thought it was a fairly safe guess. I have also stated that its original body was buy Saunders who built a batch of 250 RTs fleet numbers RT1152-1401 between 1948-50. After the war AEC produced RT chassis quicker than Park Royal and Weymann who were the allocated body builders could supply bodies so two other companies Saunders Engineering, Anglesey, Wales and Craven, Sheffield, Yorkshire were used to prevent a backlog. I recently acquired a copy of ‘British Bus Fleets’ London Transport 1965 edition and I thought you may be interested in the opening comment about the RT bodywork I quote below.
“Because of London Transports rigid standardisation scheme, most RT and RTL bodies are interchangeable. When a chassis as passed through the Aldenham overhaul works (about every four years) it is very rarely re-fitted with the body it bore previously, except the buses with GB plates.”
So it would be fairly safe to say that the bus above as a different body when this photograph was taken than when it was first delivered, another little bit of evidence is that when it was first delivered it had a roof top route number box.

RT bodies were jig built so that they could be interchanged – the jigs supplied by London Transport to Park Royal and Weymann, the major suppliers. Metro-Cammell also received jigs and I believe Saunders-Roe did.
Metro-Cammell and Weymann were entirely separate companies linked only by a marketing company MCW, rather like the milk marketing board. There were always minor differences between the products of each factory.
Cravens bodies were not jig built and were not really like the rest of the RT family. After their seven year certificate if fitness was up, they were disposed of as non-standard, as were the Saunders-Roe RTs whose construction was non-standard.

The Saunders-Roe RT’s were difficult to distinguish from ‘normal RT’s, perhaps because they borrowed an RT to design their own bodywork from scratch, but the Craven’s ones were the Standard Craven bodyframe ‘tweaked’ to look as near to an RT as was possible. However, for a start, the bodywork had five bays instead of four; the rear of the bus, from about midway upwards, curved towards the front, making it look hunchbacked, and the rear emergency window was smaller. The front profile was subtly different, flatter horizontally than was usual. The fronts were an improvement on the normal design, the rear not, the sides neutral. This was not the first case of ‘tweaking’ bodywork for London Transport’s needs: Leyland ‘tweaked’ their TD4 bodies (pre-war STD class) to look like an STL and, to the layman, it did.

I don’t know who might have taken this shot, but it was probably after 1949. The clue is the bus stops, which in 1949 Victoria still sported the LPTB design, which in turn was from the General stops with the bar circle and route numbers in large type.

The Saunders-Roe bodies were instantly recognisable from the offside by one little detail – the route number stencil was set further to the rear of the staircase panel than on the standard bodies. Personally I thought that the Cravens bodies were extremely pleasing in their own right and always liked them very much – quite a number were sold to Dundee Corporation, among many other operators, for further service. The postwar STD class, all Leyland PD1s, were very minimally "tweaked" and were a fine sight in London Transport livery and even retained hinged cab doors. Splendid indeed though the standardised RT family concept was, the exceptions were a fascinating subject, and we mustn’t forget the unhappy SRTs which I also found very appealing indeed, although their vast differences were largely mechanical rather than in body detail.

This photo was most probably taken in the mid-1960s – confirmed by the presence of the Routemasters and the advert for a BOAC flight to New York by VC10 in the background. Those were the days!
