5.3- Customers list


No list of customers or other related material has been found so far in the Science Museum 1900 archives or the Manchester 1900 archives.

Input has been sought from ICT/ICL colleagues to correct, at least partially, this gap.

The colleagues who have contributed to the lists published in Section 4.3 are listed at the beginning of Section 4.3.2.
