The Maine Maritime Museum now has on display a restored and working Stevens fogbell apparatus. It is rarely operated because of the loudness of the bell and it is located in the museum main lobby.

That's a decent sized bell Dave. I don't know of any such machines here in Oz. We have several Fog Horns located at lighthouses such as Table Cape and Low Head in Tasmania. Both still work as well. Do you have fog horns in the USA.

The fog bell at the museum is about 3-ft diameter. Some were larger, up to 5-ft or more diameter. Presently I do not believe there are any fog horns or fog bells operating in the U.S. These were replaced by electric sound signals such as the FA 232 when the light stations were automated. This current sound signal device operates from a fog detector although recently some have been equipped to be remotely operated by a vf radio signal such that the boater can activitate the signal by keying his mic several times on a designated channel. The signal will then operate for several minutes then shut off. Not much help for a boater in fog and not having a marine radio.

I recently learned this unique fog bell exhibit will be discontinued and removed sometime in late October. The entire apparatus will then be installed next year at the Kennebec River Range Lights restored bell house thus unfortunately greatly restricted for public viewing and then only on specific scheduled dates once or twice each year. This light station has very little land and is surrounded by neighboring private property lots and can not accommodate unscheduled visitors.

The slotted brass wheel behind the gear wheel in the photo below is the count wheel that causes the bell to sound from two hammer blows every 20 seconds.
