At the time this microscope was manufactured, it was the largest model sold by the firm. Interestingly, one of the objectives supplied with this instrument, a 1/8 with correction collar, was made specifically for this microscope by J. Grunow of New York, suggesting that this microscope was imported and used in America during the 19th century. As with the Merz objectives, the Grunow objective has engraved on the canister with the magnifications achieved with the four different eyepieces. The Merz objectives are a 1/3, 1/9, and 1/18 (immersion) with correction collar. On the basis of the 1866 Merz price list shown below, on the number oculars supplied (4), and the fact that it has the rack and pinion coarse adjustment, this instrument most closely conforms to Stativ Nr. I, Microscop Nr. 2. There are unoccupied fittings within the case, which most likely held a bullseye condener.
