This is 3/4 steering wheel commonly used on vintage dragsters. Like most wheels of the era it is probably a re-purposed boat or implement wheel. It is 15 inches in diameter with a 3/4" hole with keyway and a set screw. The chrome is good - about 7/10, and the plastic rim has no cracks, bends, or nicks. The shine is worn off the plastic but easily restored. It would look great wrapped in cord too. It is a Sheller brand. Buyer pays shipping from 48162.
