Double Pillar Hartnack Compound Microscope, circa 1875. Very rare and nice double pillar French antique microscope designed by Hartnack. Made by Bourgeois Opticien at 27 Rue des Pyramides, Paris, known for its production line of theatre binoculars. The microscope is in a good shape although functionally was not tested. There are no marking concerning the year of make and the designer. Quite rare collectors peace.
pretty good shape, box has a crack, the set is not complete (based on box compartments)”
