I didn't find any but another member was kind enough to send me one of his originals. So far, I have made one copy as I experiment with different processes to make these. I'm making one for him and four for myself.
Once I figure out the best way to reproduce these I may make more for other people in need. At this stage however, it's far too time consuming to do entirely by hand. I'm in the process of making a jig for the bends and a rudimentary dye to produce the threaded hole. First I need to make one more to use as a model so I can return the original and a copy to the person who lent me his. If successful, I will contact you and would be more than happy to make a set for you.
I've attached a few photos. My reproduction is identical to the original but has some tool marks that are unavoidable; the next few, through the help of the jig, should do away with that.
