The legs were given to me as a gift from my mother many years ago, sometimes they worked, other times they did not. Not sure where she got them from, but I suspect it was our creator that provided the original design. Got lost over the winter, but fortunately were returned. If I could have return them when new, I would have got Nelson Vails style legs in exchange. Beautiful legs, and lots of horsepower! As it is, I am glad to have them back.
