Full version of my profile picture. Sentry 10V in Berkeley Springs, WV at South Morgan VFD. I grew up hearing this siren, and its elegant B-flat wail is warming and nostalgic to me. On another note, I'm not sure whether the decal on the parking lot says "No parking lane fire" or "Fire lane parking no."
Long-defunct and naked single-sided Sterling in Berkeley Springs, WV on a factory-turned-shop building. There's an active 8-16 port M-10 fire siren across the street on an elevator shaft.
Fedelcode Model 5 in Paw Paw, WV. Active for fire calls.
Sentry 7V8 or 3V8-H in Shawnee Land, VA.
Defunct ACA Screamer S-10, dual tone, on my work commute in Reynolds Store, VA.
