OK, here's a solid 8 footer that I literally dragged out of a small pond. I don't know who made it, but it looks like it's fiberglass. The bracket on the back was corroded beyond use, so I am going to have to cut it off and make my own. But it also has 2 areas that are bulged, so I may need to figure out a way to repair, or if it will work as is, I'll leave alone. The feed arm is also bent and will need to be straightened or maybe I can convert to a 3 or 4 arm support, I would think all I would need to do is make sure the focal point is the same. Then just fill in the holes with automotive fiberglass, sand it down and repaint the dish. Here's a few photos:
