I can help... that looks like Dave Bowen and Darin Smith.... oh wait.. that wasn't what you meant. That is a Federal STH-10, it stands for Single Tone High...this siren has 12 ports and thus sounds a much higher pitch than it low toned brethern (A Federal STL-10.. which has 7 ports). That is a good looking siren.... I particurlary like the dual pole mounting job... that is a classy way to mount a siren!
