NOTE: Although a number of ebony quadrants of this maker are known to exist‚ neither the Peabody Museum in Salem‚ MA nor the National Maritime Museum in Greenwich in London has a brass sextant by this maker. Because of this‚ this sextant must be considered to be a relatively scarce or even rare instrument. (Source: Historical Technology‚ Inc.‚ Marblehead‚ MA).
