This B.F. Goodrich built by Schwinn Junior Miss from 1955 is very rare with only a few made during that time period and is equipped with an all original Troxel Moscow seat and 26' tires. The seat tube height approximately measures 19" from the center of the bottom bracket to the top of the seat tube so it appears to be a 20" model. Equivalent to the Schwinn Spitfire this example is a solid piece of Schwinn's historical quality and guarantee. Appears to be all original expect for rims and tires. Any questions please ask anytime.
