First up, here's an HOR S-L-8. This was an ebay purchase from Sunnyvale California. It runs off 12 volts, and has an automatic flasher for the bulb mounted on the front. It has 8 ports.
Second, here's a Sparks Wirthington (Sparton) Model 214. It was manufactured in Jackson Michigan, runs off 6 volts, and was an ebay purchase from Chelmsford Massachusetts.
Next here's an Edwards Model 315 (Federal Model A). It was an ebay purchase coming from Salisbury North Carolina. It runs off 120v. I still need to take the motor apart, oil the bearings, and clean up the junk, but other than that it runs pretty good.
And now I figured I would save the best for last: a Federal Signal STH-10B. This came from Lynndyl Utah. I saw this on govdeals after a few people messaged me about it, and with it only being a 2 hour drive each way, I decided to jump on it. It is a 1991 model judging by the serial number, and it runs great. Eventually i'll have someone replace the brushes in it, but for now it's okay.
The interesting thing about it is it was actually replaced with an Eclipse 8 in 2010? when six of the counties in the area (including the one Lynndyl is in) received a grant to replace their fire and emergency sirens with new Federal Signal equipment. I actually ran this thing up along with the 315 and HOR on New Years, and the town loved it so much that some people actually offered to help pay for a generator and trailer for the thing through GoFundMe. So far i've raised $184, which i'm not complaining. Once I get out of Job Corps in a couple years, i'll have a job which I can use to finish the project.
Due to the size of the images, the rest of them will be on my google photos. On there you'll be able to find pictures of the tags and such.
