Although not part of the ICL 1906A per se, the IBM 1130 was part of the Atlas replacement acting as a Remote Job Entry station to the Rutherford Laboratory's 360/195.
This was installed in A5 lower and in the background are the engineers offices. To the right is an IBM 1403 line printer and a 2503 IBM card reader.
This same card reader achieved fame many years later as it was used to read thousands of punch cards for Leicester Gill after they were found, when Milton Manor was being cleared out following its sale. The cards contained the results of a nutritional study from across the continent and dated back to just after the second world war. Apparently they had printed copies of the data and were debating how to get the information into a database at the time these cards surfaced. By this time there were very few card readers still in use. The 1130 card reader was still connected but had not been used in anger for some months. The software programmers put together something to take this information and put it into a database and the reader, with more than a little coaxing from the few operators still remaining that had ever seen it working, read all but about a dozen of the cards.
Thanks to Trevor Amos for remembering the details.
