I have seen this siren in person a few times and always just thought it was a Federal Model B derivative, it is located at the Stroud Township Fire Department in Stroudsburg, Pa at the Stroud Mall. I was researching another siren in the Stroudsburg area when I came across this youtube video (https://youtu.be/NT6-fgAC-cg) that is clearly of a 10/12 port siren, the description of the firehouse fits (a single story station in the middle of the Stroudsburg Mall) and it was recorded in 2014.. the Streetview shot was taken in 2016 (with a better shot of it from 2015). So what do we say, is this indeed a Castle Casting style 10/12 port siren??
