HEATH’S IMPROVED ADJUSTABLE COMPOUND MICROSCOPE. FOR EXAMINING BANK NOTES, MINERALS, FLOWERS, SEEDS, LINEN, ETC., ETC.

Boston: Manufactured by Laban Heath & Co., Patented, December 25, 1877. Two tilting glass lenses housed in a folding nickel-plated brass frame with decorative scrollwork. The microscope when open to its maximum extent is 14.5 by 5 cm wide at the base and 3 cm in height. The lens has a diameter of 4 cm. The patent date is stamped on the inside of one of the legs [diagnostic for Sullivan Type B]. Both lenses are somewhat scratched in the center; moderate wear. Item #6125

The original device, as depicted in some later editions of Heath’s Counterfeit Detector. An ingenious contraption, still quite useful. Heath touted it as a “valuable improvement in Pocket Microscopes... As an aid for detecting counterfeit money it has no equal...” Also known in a variant without the patent date stamped on the leg (Sullivan Type A). This is an attractive and eye-catching device that makes for a fabulous accompaniment to a collection of Heath’s Counterfeit Detectors.
