Hi Gang, When were Bowden brakes made and where. I have a set of very long reach side pull, that appear very old ( 1930-40's ?). I got these in the late 1960's with lots of old parts. They are very lean and slender.The spring wraps around the calipers. Did they make center pulls? They have script writing. Any help is appreciated. Craig Griffith San Luis Obispo,ca.
