Catalogue description PHOTOGRAPHS

This collection of photographs showing works and various distribution projects. These photographs have been organised through at least two different numbering systems since being created. There is no index or indication as to which was the most recent order used, and the General Manager's Office number has therefore been used as the initial sorting order and any photographs without a GMO number are at the end of the sequence.

The black numbering on the envelopes may be a works and plant number.
