Hi,..I'm Mike, and I have always liked to ride bikes, but just this last year found three old bikes in my father in law's barn. One is a 1951 Schwinn Traveler (woman's model) and one is a 1969 Schwinn Breeze (woman's model). I have thoroughly taken each apart and got them cleaned and working. Would like to know what they might be worth, and where to advertise. Also just got a 20" Monark boys bike out of the chicken coop and am working on it. Would anyone know where to find info about the manufacture date from the serial number ( A1161800 )?
