Hi list, this is another one for the long shot Dept. Does anyone know which crank arm manufacturer used the logo of three overlapping circles, the m iddle circle is slightly larger than the other two. The mark is in the cent re of a stamped in flute which runs along most of the length of the ar m, There are no other marks whatsoever on the arm, I bought it off EBay primarily for the Simplex 6 bolt chain rings and adaptor links {to 3 bolt a rm} that came with it. It was paired with a non matching French arm and t hey both had French thread Atom pedals screwed into them. I had a difficu lt time removing the pedal from the arm in question as it turned out to be British threaded. Amazingly the threads on the arm and pedal are not totall y ruined. If the arm had been alloy rather than steel I am sure the thr eads would have been toast. It looks European but it could be Japanese . Even a longer shot, anyone have a orphan LH. arm they are willing to part with? Greg Lone Langley B.C. Canada
