I don't think it's the same boat Norman, it know it looks like her, but WY.61she spent all her life, starting in the 30's, apart from war service working out of Whitby and she never had a seine net winch on her and she would'nt have been on the west side at all.
George and Elliot Duke( Marney Lunn in Leo Walmsley's books Phantom Lobster, Three Fevers and Sally Lunn) and Bob Storm Luke Fosdyke)
had her all her life and I can remember back to the beginning of the 50's and I'm sure she was still working the pots and lines when I started the sea end of 59.
Elliot was second coxswain in the Mary Ann Hepworth,Eric Taylor of Prosperity WY.59 was the coxswain and when they both retired out of the boat Billy Harland went coxswain and I started in her same time, that would be about 1962.
So if it is her it must have been a lot later that 49/50
