I don’t have much info on this E.N. Welch Clock , but my best guess is that it dates from the late 1800’s.
When this one strikes the hour, the sound of the gong is almost drowned out by the noise of the gears clattering as they spin. . . Terrible bloody racket!
The clock is American. You can find an in depth write up about the history of this clock company with the Antique Clock Guys. Other sites will direct you to a history of the New Haven Clock Company which is not accurate. We have a couple of New Haven clocks in our collection; they are much nicer than this one.
