The Kelsey Hayes company was originally formed as the Kelsey Wheel Company - found this info in one of the Wiki links... Probably means your wheels were pre-'27?

The property is the site of the former Kelsey Hayes plant which was founded by Detroiter John Kelsey in 1913 at the request of Henry Ford. The Kelsey Wheel company initially made wooden wheels for Ford and other automakers but later produced wire wheels and auto bodies. The original factory occupied only that portion of the present site located to the west of Mercer Street (Windsor, Ontario). In 1927 Kelsey Wheel merged with Hayes Wheel to form Kelsey Hayes. It was the first company to be unionized by the U.A.W. in Canada after a strike in 1936.
