Yeah imo they should've went with a new siren design or resurrect an older one with improvements (i.e. the Thunderbolt on steroids to compete with sirens like the T-135). They did, it's called the 508. As mentioned, the Equinox was a stopgap made with bits they had laying around to fulfill a specif...
A small note on "Mach", you may be missing a part. The tags on other early Federal Electric sirens would say " Type Mach . " and then have an empty spot for the model to be stamped. So really, you're looking at a "Fedelcode Type Mach. 10" in that last picture. I unfortu...
I Gave It A Try. Your Decot's upside down, mate! I wonder why the AI goes so intensely conical with these.

Of note, I had no idea that some foghorns used a siren mechanism inside, I thought they were all diaphones! This has to be one of the earliest siren-type things, right? It was active starti...
