I guess I wasn't clear enough. Harley -Davidson NEVER made snap on trim rings. The only type they EVER sold were two piece held on with 4 screws and spacers that were made for 19" wheels as part #11265-36 and 18" wheels as part #11266-36. After the 16" wheels became standard they dropped them. They last appear in the '41 accessory catalog and are gone by the '45 accessories price list. All other wheel covers and related items were aftermarket, not H-D.i pulled one off a early side car basket a while back. they might be factory just for that application.
