Doug,
Roberts & Taylor, in Eli Terry and the Connecticut Shelf Clock (2nd ed.), indicate that this label was introduced in 1822. In 1824, Eli went into partnership with Samuel Terry, so it would seem the label dates to 1822-23. Of interest, Roberts & Taylor speculate that the wording "as any kind of clock," which replaced "as any kind of common clock," was an attempt by Terry to put a more positive spin on his invention. In effect, he was saying that his clocks would stack up against any, even presumably the more expensive brass clocks of the period. Sounds like a nice find. Can you share images of the clock and movement?
