Whats the oldest fixture anyone has seen/used? For instance, take the Olivette. I've seen drawings and old Kliegl literature, but has anyone seen one or have recent pixtures? I saw some boxfloods at an old local, nonprofit theatre, but since I wasn't there to do lighting I wasn't able to get a closer look. Of course, alot of people, myself included, have experience with the old A-lamp/reflector/roundel striplight, but whos seen or used the old trough version? Additionally, old plano-convex spots pop up on eBay, often by manufacturers no ones ever heard of. I'm curious as to how these old lights look, its so hard to find examples of the earliest electric lights. So, whats the oldest fixture you've recently found yourself around?
