After putting a small list together for specific models of equipment, I hit a fork in the road when I began to search for historically accurate siren models.

I couldn't find what siren models the Los Angeles Police used from the early 1970s to late 1990s.

(If I'm correct, the modern department uses Federal Signal Smart Sirens...)

Looking into it a little more, I found the San Francisco PD still uses some 480k surprisingly meaning I can get my grubby hands on some HD recordings.

The Omega 90 was used for a time, quite rare but still used too on some older in-service specialized units in the Los Angeles PD.

I asked in a few other places and got a Federal Signal PA siren for the 70s Matador, but no specific model.

Thanks for the help btw!
