Good evening all. I remembered years ago hearing a distant siren coming from Brooklyn, CT, at the Mortlake Fire Co. From what I remembered it was 12 port single tone. Upon investigation, it appears to be a rare Fedelcode type of some kind, but a more recent Gmaps search showed it had the housing removed!
Would this be a Type Mach 1, 5, 10, etc. or something else?
Then and now pics:
