Authentic Antique 1800's Brass French Drum Microscope with Magnifier & Box

Description

I am slashing the prices on my antique microscopes because I have more coming in this week and still have others to list. Please take advantage right now and help me free up some space. :)
This is an authentic antique circa mid 1800's brass French drum microscope with the original box. These microscopes were imported to the U.S. throughout the mid to late 1800's, and so I am calling it mid century because we really have no way of knowing exactly. The importer is stamped inside the box, but the microscope itself has no brand identifier beyond a logo stamp on the top of the eye piece, as pictured. While many of these were the basic drum scope design, this one includes the attached magnifying glass for dissection.
This scope does have cosmetic blemishes on the brass, as pictured, and the box has a stain in one corner on the outside bottom, where it is unlikely to ever be seen. There are no other significant flaws to note.
Upon inspection of slides, with respect to the eye piece and objective, the image was clear and free of any visible blemishes. With respect to the magnifying glass, while it is not flawless, the glass has very minimal blemishes and is still relatively clean and clear, making this a fully functional piece for display and use.

Up for sale is this Antique Scientific Recorder made by the Brown Instrument Co of Philadelphia with a Seth Thomas lever action movement. It was patented in 1918. I’m not sure exactly what this measured or recorded but my guess is temperature or pressure. Back measures about 11” diameter, front about 10 1/4”, about 4” deep, dial about 9 1/16”. Missing its glass, probably missing something else from the center shaft. Selling for parts or repair. Both mainsprings are good and the movement has been ticking since I wound it, however it didn’t feel fully wound down, so it definitely needs cleaning and service at least. Please view all twelve photos to help judge condition.
