I think it's probably a reflection of something. If not, you have to zoom in so close that I doubt you'll be able to see it. But you should ask the TD anyway if you're curious.
As for the "Reg TM"... we've seen a few QCS so far and I don't think the others had those. Maybe you got a rep with an error. Which is actually pretty cool.
If I were you, what I would do is wait until you get it. Once you get it, contact the TD and say "hey look" and tell him to send you a replacement crown guard from the factory. This way, just in case you need one down the road, it may come in handy. But I wouldn't mention it otherwise.
