Another regulator made pounds 5,800, this one a Victorian Scottish rosewood domestic example, circa 1850, with four-pillar bell-striking movement with Harrison's maintaining power, deadbeat escapement and mercury compensated pendulum.
The movement has many refinements such as deadbeat escapement, maintaining power and mercury compensated pendulum to ensure very accurate timekeeping, as well as chiming on eight tubular gongs which give a fine, mellow but resonant sound.
