Fire engine siren

Followed up on yesterday's blip and took another trip to the fire station. Weekends are not the time to go to the station as office staff is not available so will return soon during the week. This is a Sterling 6V fire engine siren on the front of a 1936 Ford fire engine.  The siren body is chrome, and there are many out of focus reflections lights, paint stripes etc. off the siren.
