Forum member User897 has pointed us to news that some of the Diamond Select Toys new Star Trek U.S.S. Enterprise-B Electronic Vehicles have the words U.S.S. Excelsior printed on the sides. A couple of posts on their Facebook Page confirms that a few people have noticed this error as well.
UPDATE – DST responded with this:
Production error. If you ever buy your own, you can get decals from customer service. Tyjos has already requested his.
