Are you sure it was 1974 at Europort? I was on her in 1974 on the Persian Gulf/Come-By-Chance run until we escaped back to Tilbury and the ship was sold to C.Y.Tung in, I think, September 1974 (I havn't got my old Discharege Book with me at the moment).
I took slides of Halcyon the Great when she was on Tilbury Repair Jetty.
She had just changed her name to Energy Prosperity and it was end of January 1975...She had arrived there a few weeks before.
Phil I will ask Scorcher to upload to the gallery for me or if you send me your email address in a PM I will send to you.
Did you see the tug Matsas ex Turmoil - 3 slides- Scorcher kindly uploaded for me?
