This Seymour Duncan keychain belonged to my late husband....he never used it though.  My husband passed away 10 years ago which may help you date the age.  Please review the pictures for the complete description.  If you have questions, please let me know and I will try to get an answer for you.  I'm selling "as is" and do not accept returns...my husband was the original owner.

Thank you for looking.
