Mike, thanks for the reminder of 296.
As I remember, it was a one-off sample PD 2/1 in 1947, which was followed by the Brush-bodied batch 1656-1755 in 1948-49, Leyland bodied 2131-2180 in 1949 and Park Royal bodied 2181 - 2230 a few months later. Only the Brush bodies conformed to Birmingham's standards, following the prototype body put on pre-war Daimler 1235 in 1946, having the dog-leg staircase. which gave you little standing space on the platform, but gave you 2 extra seats downstairs. The Park Royals had a different cranked staircase which gave you only one extra seat, but left more standing room on the platform.
The Leyland bodies were very similar to the standard Leyland pre-war TD4c batch 964-968 of 1937, which had the Lysholm-Smith Torque convertor one-pedal control with a four-position gear lever ('convertor' position for starting off, 'direct' for over 20 mph, 'neutral' and 'reverse'), which the Corporation seemed to prefer to Daimlers immediately before the war, presumably because tram drivers found them easier to drive. The batch 211 - 295 for the Soho Road tram replacements had 'standard' pattern bodies by Met Cammell with a specially developed TD6c chassis, followed by the very handsome Leyland bodied batch 1270 - 1319, which moreorless conformed to Corporation standard.
Then during the war we had 'unfrozen' Leyland 1324 - 1326 and 1329-1331 with crash gearbox and Leyland bodies with the cranked staircase as the 964 batch, and also 1327 (Park Royal body) and 1328 (Northern Coachbuilders body).
I was always fond of the Leyland standard body. It was rather severe in design, but very sleek-looking, based on a design developed by the tramways staff at London Transport for the large batches of new trolleybuses to replace their elderly trams. Both Leyland and Met Cammell built hundreds of these bodies, but Leyland filched the design, and produced a shorter four wheel version which they offered as their standard bus body from 1937, and also offered a low-bridge version. At first they had a single tapered window on the rear top deck, but after producing the batch of 50 bodies with two rear windows for Birmingham 1270 - 1319, they incorporated this pattern on all their later standard bodies, including the wartime batch for Birmingham.
Oddly, after the war the Corporation abandoned the double window for the tapered single window on all subsequent buses built to their specification.
