A very small and unusual French ormolu, mother-of-pearl and abalone "Zapler" or "Cow Tail" clock by Leroy a Paris. Set upon an ebonised base the clock is in the form of a classical building perhaps the Opera House in Paris.The dial is signed Leroy a Paris and the movement is similarly signed. The two day movement is regulated by the pendulum that swings in front of the dial. Circa 1820.
