I have a Bing Glass Slipper from 1970. It has the very unusual Guidance System fin box in it. I was lucky enough to find a fin for it on Ebay, but I still need some anti-cavitation clips to make it 100%. I have only one. I think I need three more but would take more just in case. I am not sure if these came in different colors or not, but my box and the one clip I have are green. If you have some of these and are willing to sell, please let me know.
Thanks!
