I've got one of these old forks on my bike an I'd like to find another hub for it, believe it uses a 20mm axle through the hub, any of you guys familiar with vintage stuff know where I might find one or if there is or was an off brand that made one that would work??? I know this is a long shot but I like this old fork an would like to have a spare wheel to put some commuter tires on. Maybe someone has one of these setting on the shelf collecting dust at home??? I've been watching ebay but nothing showing up yet. Thanks
