The Siren Board

There this little thing over there in Cempuis, Oise... Nobody seems to know what it truly is, and at first I thought it's a heavily modified STH-10A, but it's still unconfirmed:

assumed to be a Constructions Electriques du Nord NP3S with modified horns, the answer is unknown for now but the motor says so, it also looks to have 8 horns.

In london ohio, we used to have a custom square horned Federal Signal 500 AT, it was CUSTOM, but the horn broke so the horn got replaced by a round one around ~2 years after the unit was installed because the city didnt feel like making another square horn

Is there any reason why they went with square horn, and also are there any photos? I am interested now

Yes, but they are gone now and here is the explaination:

Oh, i forgot to mention that i did see a photo of a 500 that an old guy had, he has since passed away and the house got burned down and unfortunatly took many many many siren and historical siren photo's with it (the stupid great grandson [who was 12] stuck a fork in the outlet and burned the thing to ashes [he didnt even get into trouble]).

That may just be another square-horned STL-10. If not, it is probably an old French siren.

as said, it most likely has 8 horns, thus im pretty much sure it is a modified Constructions Electriques du Nord NP3S, the motor also says so.

Yeah as Dorian said, it's 99.99% a NP3S with weird horns, from afar I thought it had more than 8 ports but at a closer glance, this isn't the case.

Oh well.
