Good one. After calling around and being redirected several times, I finally got an answer. A few old ones were scrapped, while the rest were donated to VFD's. I'll keep researching and calling around. I have a theory that the two P-50s with broken rotators were scrapped, along with some rusty P-15s, the STH, and possible the Alertronic. Again, this is only a theory. As of now, I do not know which VFD's they were donated to. I will edit this post as needed.
The T-135ACDC used the exact same pole as the T-135AC
