How do you identify a wilde and wessell student lamp and when it was made?

A Wilde and Wessel student lamp can be identified by its distinctive design, which typically features a metal base and an adjustable arm with a shade that allows for directional lighting. The company often used a combination of brass and metal in their construction. To determine when it was made, check for any markings or labels on the lamp, as Wilde and Wessel produced these lamps primarily in the mid-20th century, particularly from the 1940s to the 1960s. Additionally, examining the design elements and materials can provide clues about the era of production.
