Les Hamer
I didn't know the answer when posting that question, and your response is unexpected. I had not anticipated a Lancashire referee turning up in South-East London. How interesting !
Me neither, but I couldn't think who else it could be. In his final season, 1967/8, Les refereed the League Cup Final, Leeds 1 Arsenal 0. In those days, there was less regard for geography than later and I recall a Mr H Richards of Oldham came to Selhurst Park to referee a Crystal Palace game in Div 2 , v Norwich I believe.
