Although this microscope superficially resembles some models made by the Bausch & Lomb Optical Co. at the end of the 19th century, a detailed analysis if the construction suggests that this firm did not make the microscope (however, the optics are by B&L). Since except for the present example Jno Ehrmann an unknown maker, it is most likely that the 1905 engraved on the microscope is a date and not a serial number.
