I just figured since the FAA no longer has it on the registry, it might not be useful. That's my shot I put there under the current registration - to show how it used to look.
I was looking for consistency, I guess, There are a lot of my birds which when photographed had different registrations and there are no profiles for them because the registration is no longer on the FAA database.
But, it's okay to leave it, I guess :)
