I had a 66 Schwinn Panther middleweight and reluctantly sold it about 8 years ago. I was at an automotive swap meet last November and saw this and bought it. Serial # is F87917. skiptooth sweetheart crank, springer fork. tank has a dummy button where the horn would be. Bike looks deluxe, but has what I believe to be original paint on fenders. tank and chainguard have been repainted as well as the frame. most chrome parts are painted silver, I have not done much of anything to it except for whitewall tires and riding it around. I don't see any similar models with this bike's features. I'm thinking it could be a frankenbike with things added over the years, I know the light is not original, how about the seat? Rear rim is S2, although the front does not have any designation. Any help in identifying model etc. will be appreciated.
