Antique All Brass Bausch & Lomb Optical Company Microscope

Description

I am selling the Antique Bausch & Lomb Brass Microscope.
This came out of a recent estate, so I do not know much about it.
It measures 13 1/4" tall, 4 1/4" wide, and about 5 3/4" from front to back.
It is marked "Bausch & Lomb Optical" on the left foot and "29779" on the back.
From what I have read, this microscope dates to 1898/1899.
Overall, it displays well and looks to be in good shape.
It looks to be missing the slide piece that holds the mirror, as well as one of the rotating lenses.
Other than that, I am not sure if it is missing anything else.
Please ask questions if you have them.
