dunno if this lovely man is indeed Gunther Keller, and I suppose the only way of figuring it out would be to find, and view (and presumably share with y'all) his only porno film, COLT's
The Bonus. The film has a complicated plot: two ranch hands, Mike Davis and Shadow are going at it when the foreman (Gunther) rides up, nearly catches them, and decides to really make his workers work for their pay by letting him join in. Did I lose you yet?
