Amiga prototypes had several names like Lorraine, Zorro and Amiga PC. Lorraine refers to the project name (1983) and the early prototype (first part of 1984).
This machine sold at eBay had been made in late 1984/early 1985 for development purpose. But it's possible that no third developer really used it.
So we could consider it as a real Amiga prototype, a late prototype, but not a Lorraine.
And it's of course labelled "Commodore" because it had been made after Commodore bought Amiga Inc.
