Hi, I have a book "Register of Ex-Apprentices and Ex-Trainees of the Metropolitan-Vickers Electrical Co. Ltd.". This book lists 13,652 names of those who trained at the M-V Works at Trafford Park, Manchester between 1902 and 1956. The majority of those listed have mini-biographies. I am willing to do look-ups to those who can supply names and dates. Charlie.
