This is a plastic reproduction fender reflector and housing for a prewar (pre-war) vintage Roadmaster bicycle peaked rear fender. It is a replica of the reflector on a 26" bicycle, and will fit a men's or woman's bike. The dimensions, size, and shape are precise reproductions of the original. The reflector housing has been primed and is ready to be painted to match your fender. The reflector is bolted on and is removable so you can paint the whole housing and not have to mask the reflector. The screw holes are about 4 3/8" apart, center to center. $45 including shipping within the USA.
