I believe the seller to be trustworthy. However, I appreciate further providence would be desirable. Particularly when it comes to unique items from Ex-Employees…we’ve been here before! I understand they are open to questions or additional information.
I shared them with @packyman earlier. As I’d like to hear their thoughts.
Regardless, I wouldn’t be a buyer of these. From my perspective they are cool, but it’s just an error - not a “piece of history” like the prototypes were meant to be.
