Two identical ones are sent as in picture 1. Picture 2 is a section of picture 1 with a different view, but identical adapter. So, no problem

Probably only revision D is still in circulation, in case of doubt you could contact the customer service...

Hi! I ordered mine in 2011. It has H/W Ver.: B1. I don't suppose it's still the same version. Only the housing has changed completely. Greetings
