Class 117 Pressed Steel 3-car DMUs
Set Numbers
Providing a history of set numbers carried by a class is a complicated task. Below are listed the status at certain points in time; there were other variations. Each list looks at the class numerically based on the DMBS. Overall the vehicles stayed pretty much in their original formations. Thanks to John Tomlinson for this information.
Originally the set numbers were not carried on the cab fronts as they later were, but the numbers were carried on plates fixed in clips to the solebar of the power cars.
Lists are available for:

RDG was Reading - 81D (later RG) and SHL was Southall (81C).
Two example of the early set plates. James Hyde
Little changed over the next few years, by October 1965, the only changes were:
SHL 315 (51364 / 59516 / 51325) became RDG 331
SHL 319 (51373 / 59480 / 51415) became RDG 332
RDG 321 (51372 / 59479 / 51414) became SHL 319.
In late 1965 white set numbers started to appear on the cab ends of Reading vehicles, highlighted in red in the image. This also appeared on some of the early blue repaints.
January 1968
Significant changes began in January 1968 when the sets began to be renumbered. Some were still at Southall, these were transferred to Reading on 27.4.68. For the first time set numbers were in black on cab fronts using the Gill Sans font, although many retained their S3xx of R3xx set numbers stencilled on the sides of the cabs.
Sets 400 - 424 were all gangway fitted, all at Reading by January 1968, sets 450-466 were non-gangwayed and at Southall:
The image shows the set number on W51405 in September 1968.

*51357 was damaged around March/ April 1968 and replaced by 50083.
*407/408/409 numbers were allocated but these three sets went to LA in 1/68. Initially they became Laira sets 312, 313 and possibly 314. But by June of that year 51345 / 59497 / 51387 were set 304 and 51346 / 59478 / 51388 were 305, with the third set not listed at the depot, so 409's stay at Laira - if it even went - seemed shortlived, and it was listed as being allocated to Reading in Sep. 1969.

While in the listings above I've shown the depot codes, these were never shown on the front of units, only the set numbers.
1972
In 1972 there were some changes to the set numbering in that a letter prefix was carried which showed the area that the set was allocated - L for London, B for Bristol (and C for Cardiff and P for Plymouth. So Reading sets received an 'L', and Bristol sets received a 'B' prefix, as well as increasing their 3xx to a 4xx number.
The image shows W51350 carrying L458 in 1972.
