I have found evidence that Owasso used to have Thunderbolts, two to be exact. The only things I found were blower boxes. I believe EOWS 1212s replaced these; I only found the 1212 siren heads laying on the ground at a garage.

The question is, did anyone live in the Tulsa metro in the sixties or seventies and does anyone know where these were located? It would be neat to find out!
