That's Adam's picture, not mine. He can post it if he wants.

Mind posting it? Sure would be a site to see!

Yes Luke did mention that when STL takes down their sirens there might be some 500's. Did federal ever make a 500BT?

500AT (9/12 port)
500BT (9/12 port)

Thanks, I would kill for a 500B/T

What is a 500SH and the like?

Basically a STH in a 500 configuration. Eric L. has one.

I would like to put my STL in a 500 deep shroud. Talk about a bad Siren.

Next time I run that thing I might put it in the howler shroud just to see how far it will carry. Bet it would top a p-15.

I believe one of our board members Eric L. has a Model 500SH that he picked up at West Shore Services, Inc., in Allendale, Michigan. The "TT" versions were dual-tone. They were mostly manufactured in the early 1960s - the early 70s.

All of these post are correct. What the abbreviation means is 500 single tone high.

The Model 500SH was a single tone version of the 500, which used an air intake from an STH-10. A Model 500SH TT, is a 10/12 port dual-tone version made in the 1960s.
