Here are two examples of the Queen Universal Household Microscope each dating from the last quarter of the 19th century. They
have a bronzed iron base with the signature “James W. Queen amp: Co. Philadelphia” within the casting. On the left is an example of the most simple
version having push-tube focusing and a non-achromatic objective and on the right is the most advanced model having rack and pinion focusing, a
triple button achromatic objective, and a tube-mounted stage condenser. Each microscope is supplied with a wood storage case.
These inexpensive microscopes were sold to hobbyists. They were likely manufactured in France and imported for sale into the US.
The microscope on the left corresponds to item 3061 in the catalog, the more advanced example on the right corresponds to item number 3064.
