You will be able to get a lot of info from the records at North East Lincs Archives, if or when they`re open to the public.
I`ve a notebook of my father`s from when he was looking for someone, where he`s listed who the trawler belonged to ( wrong grammar, but it`s late !! ) and I "think" who collected the wages . I`ll look tomorrow to see.
To continue ! It says Fishermens agreement with number. There are the names of the trawler and it`s number, which port it sailed from (in this case Grimsby) also with number; the name of the person who collected the wages, in and also the trawlerman`s address.
It was quite a lot of years ago when my dad did this; I think it might have been from the original, but he hasn`t written it down.
