Hello!

This is the genuine vintage Atari Service Authorized 5200 Retaining Ring for the joy stick controller.  Usually these are damaged when removed from the controller to repair the controller boot or most any repairs that require the removal of this part.  These ring are rare in this vintage original replacement part condition.  If you have any questions please just let me know.

Atari Part number: C018116

You are purchasing 1 (one) ring.  I am making only a few of these available at this time.

Thanks!
