This address is where Nachet had his shop between 1839 and 1862.
All mechanical movement is excellent.
The finish is polished brass with a black painted metal base. Some parts, such as the brass on the mirror, have been oxidized to reduce stray reflection. The concave mirror is good, but shows some wear around its edges. The microscope comes with one objective marked number 1, and one eyepiece marked number 2. The optical system is equivalent to 100x magnification.
