This album may well have arrived with staff who transferred from TRE to AERE. The photos are glued onto thin paper so it is usually possible to read the stamps on the back by holding the page up to the light. Photographs are stamped variously with "TRE Photographic Group" and/or "Applications Dept" and "TRE Malvern." Photos are listed according to their sequence in the album.
