I'm seeing the images just fine

This looks to be a very early Federal Enterprises era Model 5 (single phase as well), especially as it does not have any holes cut in the stator top to attach coding gear. When you look on the shroud for a motor tag, also look for another large badge that says “Fedelcode” or “Federal”, as if it has...

It's amazing how far sirens have come in innovation. It takes far less power to run a T-135DC than that old P-50.

I wouldn't mind having a P-50 in my back yard though - I could get a big enough genset to run it =D

Very nice restoration! I saw a video of one of these units on YouTube the other day. I had no idea they were a thing until then.

For heating up frozen fasteners, a tool I'd like to get is an electric induction coil that wraps around a nut or bolt hex. I read about it in a Hagerty news article. It would beat burning up everything else around the f...

Looks like an alien falling out of a spaceship somewhere high up - LOL!

If I did it again I would've brought an engine crane with me to lift it into the back of the truck. That would've saved us some effort! One of the 2-ton Harbor Freight cranes boomed all the way out would do the trick.

Are Fedelcode and FS Model 5s the same thing? If so, my Model 5 weighs around 300 lbs and needed four adults to lift it into the back of a pick-up.

I can't remember the exact location, maybe at the bottom of the shroud judging from the picture I have, but on mine I could make out some electrica...
