colingolf, I knew your Dad the photo was taken on Proto Section, although the work they did was toolroom quality they were not toolroom personell, but production workers and could transfer to a toolroom job vacancy as skilled men, as i said i worked in the Works Engineers dept my knowledge of your Dad would be if i was repairing his machine or another on the section and saying "hello" and "how are you", the others in the photo would know him well, i still see some ex-BW5 workers and will ask about your Dad.
