I'm selling a vintage 'Bird' lapper for skateboard trucks. The Lapper makes a vintage skateboard setup even more complete. It was intended to help prevent hangups with the back truck on copings / curbs. These are old, and the plastic may be cracking on the edges in some cases. As a result they cannot be guaranteed to take any impact, and may be best for display purposes on your vintage complete wall-hanger. Thank you for your attention to this.
