Well, I will tell you, I don't have a picture. However, it does appear that the mechanism which allows that top to tilt back is not there. Not much to it really, just a round looking hinge coming off the end of your conduit which screws into that top piece with the hole in it. Have you ever seen those silver colored folding light sockets that are adjustable that they sell at Lowe's? It would work the same way, that's what the hinge looks like. I'm at work in a boiler room, sorry I can't talk much today, fixing a high pressure steam leak. Good luck
