This is a vintage Frederick Cooper of Chicago-style brass student table lamp according to a AI search.
This style of lamp was sometimes manufactured by companies like Manhattan Brass Co. and Frederick Cooper of Chicago
This item is a 
student lamp, which is a type of lamp often made of brass and designed for use on a desk. The name comes from their popularity in the late 1800s, when they were used by students.

I believe with some polishing and gentle cleaning that the brass will really shine.

Some people want to keep the original patina. Either way you go, you will have a gorgeous lamp!

The glass lamp shade/chimney is included.

This lamp weighs almost 5 pounds.

[does not include lightbulb]
