Quote ="Bulliac"We have a few Davies's who played for the Northern/Bulls over the years, including a 'Derek'. He played a total of 139 games, scoring 37 tries, covering 7 seasons from 1955/6 to 1961/2, so it's unlikely, though possible, that he's the one you describe. I haven't any other details though, other than the basic ones already given. There is no other likely candidate for your Derek, not even any vague 'D' as we often get with many of the old names.'"
Much appreciated Bulliac, I will pass the information on to my pal, he definitely played for Hull, but after this we are drawing a blank, once again thank you for helping.
