Federal Signal PA-300 Siren 1/10 w/ Covered Speaker

This is one of my PA-300 sirens. I have another video of this siren without the towels over the speaker. As the title says, I have 10 of these, but they are not all the same. Most of my PA-300s have the older style tones as heard here, 5 of those being the silver models. I have only one equipped with the Priority tone, all others have Hi-Lo. All but two of the sirens operate, the other two need to be fixed. Only this and one other siren have working backlights, but the other is one of the ones that need repair. None are for sale at this time. I'm planning to sell some in the future and will post a more in depth video of the siren being sold when that time comes.
