Ok, so I pulled this from an old unicycle, but it was obviously a replacement (or so I think). It was a 60's or 70's uni, and I have been told by a bmx collector that this is one of the earliest skyway clamps ever made. It has an S on the binder bolt, but is not Schwinn style. Unless it is an 80's Schwinn, but I haven't seen one like this before. Let me know what you think. My gut still says Schwinn, but this does have a bmx look to it with the different more blocked S, and the flats on the binder bolt sides. The chrome also seems more shiny than what Schwinn used in the late 70's-early 80's. Thanks for any help.
