Greetings,
I have recently acquired a Federal Enterprises Model 5 siren. It fell off the roof of a building during a windstorm in spring 2017. The siren was painted silver-gray, which appears to be a common color for these units.
Fortunately, the motor, chopper, and stator were undamaged as its lifting mount broke its fall from two stories into a grassy area. However, its outer shroud is smashed up. While I could remove the top easily after snapping off the rusted-on lifting eye, it took me an hour and work with two crowbars to work the warped cover over the siren.
I discovered and cleaned the motor data plate and found the following:
Federal Enterprises Chicago IL
3 Phase, 208 Volts, 60 Cycles
5 HP, 3500 RPM (hard to tell the RPM due to age)
Type AV37X, S/N R618759
There is some kind of Rise PC number I cannot make out.
Does anyone know how I can tell when this siren was manufactured? I'm guessing the early 1950s. What do the Type and Rise numbers mean? Also, does anyone know where I can find a new shroud or have any sheet metal fabrication plans for one?
