Pugilist 'Top Thumps'. Bare-knuckle boxing game.

The game is based in the pre-Queensbury, Bare-knuckle era where fights were often bloody, gruelling affairs that could last over 50 rounds and take many hours until one fighter was knocked 'out of time' and unable to make the scratch.
I'm told that the designer of this game is a student of BKB in England.
