1940's Brooks leather seat-Very nice. Made in England. Asking $100. 1960's Banana seat with sissy bars-Very good condition. There is some minor surface rest on the chrome that may be able to be cleaned up. There is no name on it that I can see, but my friend claims that it is a Schwinn and it does look like other ones online. Asking $125 1980's BMX Grand Prix hard plastic seat-Great shape. $65.
