Help Identifying a Beacon

[SP7134]

So i was searching around facebook marketplace and came across a person selling an old tow truck boom and it had this beacon, i asked if they would sell it apart and they said yes for 100.

i was wondering what the make and model of the beacon was, as well as if it would be worth to purchase for 100.

from my limited knowledge i think the dome is that of a federal signal model 14 but i could be wrong, help would be appreciated!

Dietz Model 7-40/41 with a Federal Model 14 dome on it.

If the dome is not cracked and just needs to be polished you can't go wrong for that price. The dome alone is worth at least that much but probably a lot more because the blue ones are really really hard to find. Buy it if you like it or someone else is going to jump on it. And if you do decide to buy it find a nice Federal Signal beacon to put it on and you will have a very nice light worth some good money in today's market.
