The box contains English Electric negatives in printed envelopes. The origin is EE Bradford or Preston and all photos are of locomotives, electrical control equipment, and components in sequential bundles. They are listed by group or set of photographs, not by individual photos. A sample from each bundle is detailed. It was noted that some individual envelopes were designated B/C and some P/C. The reason for this is surmised to refer to a Bradford or Preston origin of the photograph.
