Beacon identification and questions

I picked up a NOS beacon but I dont know much about it. I am not that into beacons or most mini bars for my collection but been wanting a 2-4 sealed beam light for a while. Unfortunately I drove too far picking it up to pass on it.

What I know,
Model is a Federal Signal MS-51317-03 and says 28 volts. Dome has F2 on top.

What I do not know (or not able to find out with some quick searching)
The beacon or dome model. I found the dome for this listed as a model 11, 14 and 100. (Is the whole thing a model 14?)

With it saying 28 volts, does that mean it is designed for 24 volt systems?

Its general age. IMO it looks too modern to be 30-40 years old. I would just guess at it being 10 give or take a few years.
Feel free to add whatever.

At this point I plan on selling this one and finding a better fit. Any idea on the value? It looks like the dome is at least worth a bit even if the guts are not.
(Feel free to pm me an offer if you are interested). I plan on listing it soon but knowing its value (parts or whole) would be nice.

The model is a military version of the Federal 100 which is the modem version of the 14. Different motor (newer) and gearing from the model 14. 28 volts means just that.

Thanks. I did read that thread during my initial search but it didnt clear it up for me (confirmation of model number or proper voltage).

Will the dome fit a model 11, 14 and 100? Any others?

I presume that this is similar to the Aerodynic, Aerohawk and Aerotwin in that they have the same frame/dome but the guts determine the model? My main knowledge is in full full-size lightbars, not beacons like this.

Thanks for the replies.

Because it has 2 sealed beams it's actually a military version of the model 14, the model 100 had an open single reflector similar to a Sentry. Before it was discontinued the model 14 was available in both an aluminum and a polycarbonate base. The 11, 14 and 100 domes are interchangeable.

Thanks for the info!

In looking inside the light it appears to have a standard Federal Signal rotator moror with a different gear (and being 24 volt). Is their any reason I couldnt swap the motor/worm gear with a 12v motor (and lightbulbs) to make it function on 12v?
