One day marine chronometer in mahogany box by John Roger Arnold no. 356, circa 1810. The plain mahogany lid has brass butt-hinges, opening the lid to 90° to reveal a glazed panel retained with narrow wooden beading. The inside of the lid has pasted in a label for chronometer maker James Pyott, and the glass has pasted on a cutting from an auction catalogue, the entry reading: “An Old English ship’s chronometer, taken by Sir William Parry upon his Arctic expedition in 1818”. There appears to be no evidence to support the claim that this chronometer was with Parry on his Arctic voyage of exploration in 1818.
