I removed this seat from a 1971 Schwinn Collegiate. I could find no manufacturer markings. It is a double sprung wide seat that has Schwinn mounting hardware. The covering and the undercarriage look good. This looks like it would be a nice comfortable seat for your rider or project bike. The springs have very light surface rust. I am selling it as is with no returns, so look closely before purchasing. No international sales. Thank you for looking and please stay safe.
