I bought a hanging light at auction, unfortunately there are pieces missing. When I went to research the piece I was able to figure out that the light has never been in production and was a prototype probably shown here at the "world market" (a wholesale trade show place). The light itself is fine but I will need to buy a canopy, and connecting tubes to hang it. Being that this is a prototype I guess I am free to use whatever pieces I want. Does anyone have a good lighting parts store (online) that they have good luck with?
