The architectural pediment with a panel of open fretwork beneath is an unusual styling touch, and very successful. Dentils are used in the cornice mouldings, with a classic Greek key pattern just below the hood and laced frets across the impost above the trunk door. Fine flame mahogany veneers decorate the trunk door and front of the base panel. The trunk's quarter columns are fluted, with stop-reeding carved in their lower sections. The base section has canted corners, carried all the way through into the form of the feet.
Color is a deep and rich brown, with a fine old patina.
The center of the dial is profusely engraved and silvered, with the calendar in a square aperture at the bottom. The blued steel hour and minute hands appear to be original. The brass four pillar movement is original to the case and dial, of eight day duration, with hourly rack striking, strike repeating, and calendar work. Escapement is anchor recoil, and the weights are lead. Joshua Harrocks is listed by Baillie and Loomes as working in Lancaster from 1748 to 1764, and later in Eamont Bridge, Cumbria.
