I had posted a question reguarding which Dearborn Sirens were which. They are all Whelen Omnidirectionals and installed around late 1980s, or 1990 thereabouts. I have included some detailed photos of the Exact 2 types of units near my house because I want to record the eldest or best of these sirens.Any help would be great.
Siren #1 has 5 driver cells in the middle and also has "screens" between the cells. It is the only one with the screens like this that I have seen. I have my eye on this one. Is it at 2700? something... Id like to know the exact model.

Siren #2
is the most COMMON type, I have found around at least 10 of the 29 sirens are this type with 4 cells in the middle and more of a "hex" look upclose than round.

Siren #3
As found on another site, this is on Millitary Avein Dearborn and is similar to siren #W1 with the 5 drivers, but no screens. Whats the differance?
