Under customer it says, Demo and in the comments section is simply states, Entwistle.

If you are registering a used bass and want any additional details, you need to let us know in the comments section of the form. Otherwise we just record the new owner information in the file.
The case looks original too. We still use the same casemaker, but the fashion has changed a little. Have you ever seen one with a bright orange interior? It's actually pretty cool.
