John D. Nutter made clock in Mt. Vernon New Hampshire from about 1820 to 1836. I don't know too much else about him, but the this at least helps date your clock.
At the same time, there was a E. H. Nutter, in Dover, NH, also making clocks. I'm guessing they were related, but not sure how.
If anyone knows more about these NH clocks, or their makers, I would be interested to know.
