I took that photo. Got the exact date here if required. Also there on the same day were three old Helyer trawlers from Hull. I'll be pleased to upload my contributions presently. Great forum.
The photo was sent to me as the webmaster of the Tyne Tugs website. Unfortunately I had a hard drive crash on my last computer. I had all the photos and data backed up except for my email files. So I lost all my carefully saved and categorised emails which would have identified who had sent me the photo. I apologise for forgetting your name. Thanks again for the photo.
