Ben, Kyle and I went out to Shamrock, TX to get a video of their 1003. I was fairly confident that this siren wasn't going to operate at all, given its in not-that-good condition. It appears to have fallen down or blown over at one point, and has brand new-ish looking hose clamps keeping the standpipe on the pole. Shamrock also has 2 Federal SD-10's, located at opposite ends of town. Testing consists of Attack/Hi-Low Attack.
