These sweet knobs are metal–not the plastic we see most of the time. The bright painted knobs are from the Art Deco period of mostly the 1930s to 1940s. The reason we know these to be older is because of the way they were made. The top was folded over and crimped to the under base, and then that was applied to the neck. It was a labor intensive process which we don’t see in the later knobs.
Each knob measures one inch across the top. The base is 3/4 inch and has grippers on the underneath side to adhere to the wood. The knobs project 3/4 inch from the surface.
These red knobs with the white circles scream of the older days. This set could now be used on just about anything, or separate them and show-case one in a special setting.
