I remembered the moment I saw a presumably a Federal Signal 500AT Prototype in a YouTube video (I said "presumably" since IIRC the title said about the particular siren) but failed to relocate it at both Google Images & YT. The siren has a short horn, just like the series A and/or B we...
The recording of an 8-Port Mobil Directo is exist, but IIRC the only one is the one at Milwaukee, WI, a gas-powered variant which turned electric. Anyhow, Dennis, 1. Assuming there's no Gas MD recording around, could we see a video of your museum unit running from start, engine running, signal then ...
Directional choppers can only go in one direction to make the most sound. It's when the vanes for the ports are directly at one end, like on an ACA rotor. Federal Signal rotors are non-directional, as the vanes are in between two ports. Any German, British or any euro siren will have a directional ...
I think the well pump Thunderbolt was located in Melrose, NY, I've seen pictures of it but sadly they're gone. EDIT: http://www.civildefensemuseum.com/sirens/Melrose%20Siren%202.jpg Strongly reminds me on the Protobolt (Prototype Thunderbolt portmanteau'd by me). I bet this is due to motor burnout....
The only way we could take; ask Jim Biersach. That if he's still alive. Edit : I couldn't email him. I'm now on my Nokia during morning tea at boarding school, no idea on Jim's email address & my Compaq Presario V3000 (Remember my driver issues while trying to run ROBLOX Studio?) is now dead (So...
I'm not sure how one could elegantly fit any damper mechanism over the intake bell. I'd might suggest B&N put the damper in the neck. I've once thought about making a 44E Hi-Lo capable long before this thread by shutting & opening the rows of stators actuated by some sorta geared wheel or a...
That sounds like the text on the ID plate will also come off. Are you sure only the outer layer of the paint that painted over the plate will be the only layer affected?
Ditto with Alfie. Unless you'd like to do some research or fun, you'd better get an original Model 2 Federal Signal made rather than a counterfeit. I once have a fake Nokia 3310 (The one I have right now is the original) (But now lost at the ironing room of my hostel [Fake one] when charging there; ...
