When I got closer, I was presented with another surprise: this giant Fedelcode siren!


Sadly, considering the new siren sitting only 20 feet behind it, I highly doubt this one is being used anymore.
I've seen at least one other picture of a similar Fedelcode, but I don't recall seeing a model number on it. It definitely appears to be a dual-tone siren. Perhaps this is the ancestor of what eventually became the Federal Signal 2T22/3T22?
Oh, and just a quick question: is there a way to visually differentiate between an ASC T-128 and T-135? Comparing their pictures on the ASC website, they both look virtually identical to me.
