I found a box of roller skates and roller blades in an attic, no telling how long they were up there. I know absolutely nothing about these but took a lot of pics. Theres lots of wear and scuffs and rusty parts but the wheels seem to roll fine, they don't roll freely though when spinning with your hands, have to keep spinning them. These are a size 7 and might clean up some but will not look new again, lots of wear. They have Linear on them. Thats about all I can help you with ...Thanks for looking
