Antique massive brass Gamewell Faraday 13 fire alarm box bell telegraph

A large brass alarm bell mounted on a cast iron frame, the bell is 13" across and quite thick, the entire instrument is about 15"x 20 overall and weighs over 21 lbs. It appears to be in very good condition, but is untested. Apart from some illegible stamping it's unmarked, I'm told it's a Gamewell bell, and the acorn nut securing the bell seems to fit that, but I do not have direct knowledge of the maker.

A large and handsome piece.
