This one would be the newest member of the group, since it hasn't even premiered yet.
I think skullturfq's entry is a bit off the mark, but has the right idea. Dobie's is a valid entry, though the matching member in the other set is obscure (as is mine).
That's assuming that the other set isn't further qualified by company. I'd be able to figure that out if I could ID Ken's photos #1, #3, and #4. I had pretty much figured out what the set was going to be just from photo #2, and figured at that point #6 would be there somewhere.
