Genuine Jubilee Bracelet?

[TimRolex]

Happy Friday everyone! I am hoping someone here can set my mind at ease about a replacement jubilee bracelet I just received for my wife's 36mm 16014 DJ...pics attached (sorry for the quality, iPhone).

I purchased this bracelet because the original was just too stretched to size correctly for her small wrist. I bought it from a reputable seller, but he had to source it from someone unknown to me. I have a few concerns.

My specific questions are:

Is there anything in the pictures that should raise a "red flag?"

Is this how a replacement bracelet from Rolex would come packed?

The end links - 555 with a "B" below them...I always thought the 555B would have the B right beside the 555. also, my understanding was that the 555B end links should have "open access" to the spring bar, because they were designed for cases with no holes.

The 011 clasp code - I can't find any information on that.

Any insight you could provide would be extremely helpful!
