Check the listing for details. Vintage Glasspar Boat Part Wheel Cap Steering Wheel Speedboat Ski Boat Marine. Condition: Used, Made in United States. Listed at 22.00 USD. Cool old Glasspar Boat part. Unsure what it goes to. Both pieces made of non magnetic metal. Insert with Glasspar logo is loose. My guess is it goes on a trailer wheel or boat steering wheel? If you know please inform me. See pictures for condition, color, graphics, text, details, markings, measurements etc. Reasonable offers considered. Thanks for looking.Cool old Glasspar Boat part. Unsure what it goes to.
