The Siren Board

This is an STH-10 located in front of the Riegelsville Borough Hall in Riegelsville, PA. The reason there is a cone like piece on top is not for protection from the weather but custom made to have the sound travel down the hill because the Borough Hall is located on top of the hill and the rest of the town is on the bottom of the hill.

That is one special modification. I've seen skirted 2T22s and Model 5s with horns, but this is just amazing.
