I sold my FS-128 awhile back and have these items left over. An FS-128 Clamshell Tube holder with a TV Starbeam and piggy back adapter professionally installed. Asking $300 obo. It is in great shape. I also have an FS 102/128 Camera Angle Adjuster that is in good shape for $135 obo (this has been sold).
Thanks for looking!
