Pre WW2 Rudges back to the twenties often (always?) have A & P on the head stem if my memory is correct. I should have looked to see if the other tubes in the set were similarly marked. In their catalogues, Rudge did not name the tubing manufacturer, but specifically described the tubes as chrome molybdemum so I have always assimed that shoudl I be lucky enough to find a .late thirties Rudge lightweight it would be in Accles and Pollock Kromo. While typing this, I have fished out a Rudge catalogue for 1938 and find that the top of the range "Olympic-Aero" was in named tubing... Reynolds 531 butted. I believe Lauterwasser was responsible for those particular bikes. Any comments on the respective merits of the two makers at that time? Anyone who lived in London in the fifties will remember Accles and Pollock for their tube train advertisements in which almost every mistaken rendering of their name was given. As ten year olds going up to town from South London, we added a name of our own so consequently I always pronounce Accles and Pollock as Tackles and Bollock.
