It's a "wery rare collector item!!" too. Seen similar things with Eye Jackets, where the stems don't match the orbitals. They didn't get the memo that a one-of-a-kind custom/hackjob isn't the same as a one-off production model.
This kind of fake really should not be happening. It is really sad for the person that buys these. It is a fake c six already up to 1100 dollars. I wish I knew how to report this.....
It looks legit enough from the pictures, and if his story is to be believed, he's selling off unsold models, and probably just throwing them into whatever case he had at the store.
