Eddie and son hence Edison, top class machines, both worked at Carlton I believe, often the fork and rear seat/chainstays are finished in the Carlton open end way. Pretty sure all were built to order in house, they did TT, road, tourers, CX and MTB's I'm sure.
Thanks for sharing that email Ian, may drop him a line at some point, although to be honest, I probably know all I need to know so may just leave him in peace. Either way, it's a lovely frame to ride. Your Low Pro looks, well, agressive to say the least!
