Here's a few before and after pictures of the Federal Model 28 siren that I've been restoring!! I'm pretty happy with the way it came out. One of the bearings was starting to seize and was difficult to turn to I just soaked it in PB Blaster and repacked it and it turns great now! I'll eventually take a video of it running and upload it to YouTube!!
Here's part of my siren collection... You can see the Model 28 in the top row second from the right...
Taken apart..
Back together and painted!!
