Here is a vintage floor sander made by the American Floor Surfacing Machine Company of Toledo, Ohio. This company, which was in business from at least 1909 through 1957, was known for their floor sanders. They also made a combination machine known as the Electric Carpenter. They also made handheld power tools (sanders, circular saws, and chainsaws) and machines for surfacing concrete and terrazzo floors.
