Jamie72 had this posted up in another thread (not sure if its his or not though), seat on its not right but its a match with the steelies.
the brochures usually show them with 4" wheels this is an older add thanks to the minidoodle site:
The powerdyne wheels will look good on it Will ave that Manco look and looks like they used a Band brake so you dont have to futz with figuring out some elaborate brake.....unless you into that sorta thing
Manco was around a long time, in the beginning they were using the "Little Gen" name on bikes which was a bike built in Fort Wayne Indiana in the mid 60's. I dont know if it was the same company that just renamed or something was bought out or what but the manco name shows up in the later 60's and of course held on until recently.
