No remains as far as I know. :( Damn, I wonder if there is any documentation that there was anything installed left. The one on the Johnston building was the last one.

When did they get removed?

Early '90s

I figured I would post these bids from 1955 to 1956

These are newspaper clippings from The Charlotte Observer

Here are some pictures of the DHTTs

Weird. I check all the places and I did not see ANY 500-DHTT.

That's because they were removed.

Charlotte had four other 500-DHTTs at these coordinates:
35.23773, -80.81641
35.20264, -80.82223
35.20769, -80.86169
35.24102, -80.8616
They were from 1955, the one that was on top of the Johnston building was bought the following year. They were all roof mounted.

It was located on Puritas Elementary School according to the seller, here are pictures from the listing.

There was a gridface Thunderbolt horn for sale on craigslist in the Cleveland area not too long ago.

Yes, that is a Model 20, nice find!
