Other inventors/makers
Here is a selection of leftover designs, some of them one-off hybrids (such as 182), some single examples (such as 181, 165, 174, 155, 164, 169, and 166) some owner-made (such as 144 and 45) and one pair of braces with two equivalent patents by different inventors but made by the same company, a violation of patent law: 114 and 154; both inventors claimed to be the sole inventor.
