PEISANDER, PRIAM and GLAMORGAN at Vickers? The Swan's tanker on stocks, not sure, NARICA and BRITISH ARGOSY both around that time. OLEANDER in the middle?
The RFA near the centre would be Lyness, George - launched on 7 April. I'm not sure of the tanker at Swan's Wallsend yard - British Argosy had been launched in February and would be out of picture to the right.
