I think the company you may be after was Sutherlands Spreads, which was owned by Quaker Oats, who sold it to Shiphams. Shame because Sutherlands were far superior.
I think androcles is right , as soon as I saw the name it came back to me, they used to do meat pastes as well as fish and i seem to remember that unlike Princes or Shiphams who only sold it in jars you could buy it by weight
