Second photograph of the floating dock at Portsmouth. See comments/query posted on the other photograph I have submitted.

One of two photographs of a floating dry dock at Portsmouth. Can anyone identify which one? My best unconfirmed information that this is AFD 5, built in 1912, which was destined to be moved to Alexandria in 1939, but only got as far as Malta where she was sunk. Anybody able to identify the tugs?

Dock workers under the Kaitoa 1968. The dock workers had a reputation for restrictive work practises.
