Here is a hub or similar cast cover from some unknown piece of machinery or equipment but I had to go looking for more info on the company. I've never run across any Maxwell equipment that I can remember.
Maxwell's Limited was a foundry first established in Paris, Ontario which moved to St. Mary's, Ontario in 1888, where it became known as David Maxwell & Sons or simply Maxwell & Sons.
In its heyday when cast iron was king, it employed over 100 people and was the largest factory in Perth County. The two-storey building was 250 feet long, with another wing 200 feet long. The first floor was for machine work with storage in the wing and basement. Painting and finishing were done on the second floor. Three shorter wings, each 150 feet long, contained a wood shop, blacksmith shop and moulding shop. Initially, farm equipment was the main focus, but eventually it produced all sorts of horsedrawn equipment and farm tools down to wheelbarrows and butter churns.
During World War II, production was devoted to the manufacture of hand grenades. Following the war, it was unable to compete in the farm equipment field and ceased operation in 1964. The factory was demolished in 1987.
