The Siren Board

Hello
A few days ago i buyed a General City Signal Model 351.
I searched the internet for infomations about this Siren, but i didn't find anything.
So if anyone here can tell me something about this siren, it would be very nice.




Any guess when it was manufactured?

Thanks for your answers.

basiclly what you got is a relabled Federal 66L. Looks identical to the one I have, except mine has a dented back by the name plate. Great sounding siren too, sounding a bit lower pitched than a Q but with a quicker wind down. As for the date, I'm not sure, I'm sure the vehicle siren collectors on here can tell you more.

The stator openings do not look like a Federal model 66. It appears to be a re-branded model WL. To check measure the rotor diameter, a model 66 has a 6 1/2" rotor, a model WL has a 5 1/2" dia. rotor.
