I have a brown Jetstar that is an early 1959. Serial number 3 to be exact. It has fenders on it that are different than models like 335, 445, 5 Star or Jetstar 2. They resemble the mini clamshells of a late R. However they are much lighter built and very bent up. These fenders are bolted to the brackets with two small pieces if C channel sandwiched in between. Thus making the fender sit on the outside of the bracket. This looks factory but I have not found any pictures to verify it. Just wondering if anyone else has one in the same configuration. Also, on my build sheet, it lists an option #11537, which is not present on the options list that comes with the build sheet. The best I can figure is that must be for fenders. Can anyone verify this? Thanks for the help.
