Hi jkbaus,
From what I can see on the net both A & C are window seats with A being right next to the window and C being a seat width away. Take a look at this link for a pic that will show the A340-600 J cabin. It should show what I mean

Apart from that......seastguru seems to imply there is no 7A as well on the A340-600.
I'm pretty new at this but thought I would try and help as i have been trying to get similar info.
Good luck
