Burdick Group Patent Drawing, Patent No. 4,382,642

Here's a very interesting item - the drawing filed with the U.S. Patent and Trademark Office showing the complete Burdick Group system (or at least most of it). The patent has expired for the Burdick Group per my research. Will anyone build it again? Probably too expensive to launch as a consumer product. All main metal components were of polished aluminum. These included the beams, bases, and brackets. Questions? Selling or buying? Email me.
