A bit on clocks of the style of this one. They are traditionally known as "New Hampshire" mirror clocks as they were predominately made in New Hampshire. Truth be known they were made in smaller quantities in Mass, Vermont, and Maine, as well as New Hampshire. They were made in limited amounts for only a short period of time, most likely as early 1810 and as late as about 1840. There were maybe 30 or so makers of these clocks outside New Hampshire spread all about and a similar number of makers in NH. Very few of them ever achieved or attempted, true mass production. Most of them reflect old-style clockmaking, often rather clumsy execution, a lot of handwork, sometimes iron plates, and some very strange striking mechanisms (rat trap strike for one). Charles Parsons deals with these clocks extensively in his book on New Hampshire Clocks and Clockmakers. At the time of these clocks Terry, Thomas, Ives, Jeromes, and a number of other folks in the Bristol area began producing clocks by the thousands and they were far cheaper than these clocks that were hand made in the New England area.
The subject clock in this thread would have hung in a pretty formal house, most likely in NH, and built post-revolutionary war +/- a bit. Many earlier houses tended to have lower ceilings and would not have had a good place to house a clock this tall, at least not gracefully. These traditionally hung in central locations in houses where they could be seen by the occupants easily. They would not have hung in the keeping rooms/kitchens, nor in a bedroom, nor in the parlor. The parlors tended to be reserved for special occasions by many families when space and $$$ allowed. Sometimes weddings and funerals only. So, these clocks may well have hung in a central hall or in the front staircase when there was no central hall.
And yes, I have seen the movement of this clock pictured elsewhere, but I have spent at least 4 hours looking for the subject photo/article all to no avail, so far.
Most of these clocks stayed pretty close to home as none of their makers attempted to sell outside their locales and their limited production did not flood their local markets to any great extent. Much unlike what was going on down in the Bristol Conn area at the same time. I suggest how this one came to reside down south would focus on its more recent history, not original ownership south.
My credentials to run my mouth on these clocks? I have owned/restored/repaired/sold 30-40-50 NH mirror clocks and spent 10+ years in NH during which we were able to restore a couple of 18th-century houses all while buying and selling, studying 18th/19th century NE architecture, restoring clocks, etc. So, all that might buy me a cup of coffee on a good day.
Your clock came out quite nice I think. Congratulations!
