Reply from Michael - came to the webmaster address:
Sorry, I had enough people to make One last batch of these earlier this year. Because of economy of scale and minimum charges it’s problematic to make less than three at time. I don’t expect to make any more. I don’t have drawings, I just copy the one on my trailer. There was a lot of cut and try to get it just right when I made the first one. I do use it to lower the mast too.
