G. Rice and Wm. Johnson were doing business at 106 Vessey Street in New York City ca 1840. Apparently they were wholesale/retail dealers and not manufacturers. Note that 1840 was the end-of-the-line for wooden works clocks. Clocks with case doors made of cyma curved mouldings, usually veneered, have taken the name OG, the name of the cyma moulding.
