1990 key chain

[ZR11974]

Good afternoon, everyone. I recently purchased my first 1990 ZR-1, and it is a one owner. He had almost everything that came with the car. He even said the keychain the keys were on was the original key ring, too. Apparently it used to have a Corvette emblem inside the metal housing, but he said it fell off years ago. I've attached a picture and since I can't find anything like it on the internet I thought I'd put it out to the specialists, here.
Anyone recognize this keyring? And, know where I can get an original replacement?
Thanks, and take care.
