History of Gamewell vs Richmond

Hello. I am the curator of a very small historical society in northern PA and we were recently given an old (well, probably 1970s) Gamewell fire alarm box. Doing some research, I find that this system was adopted by our city in 1888 but the City Council also favored the “Richmond” system. I can’t find any information on that system. Can you help? I like to be accurate when I present my history.

Gamewell was owned by a company called gulf+western in the 1970’s
