Looks similar to late blight. How are the plants doing?

If it is late blight, they should be pretty much in the goner category by now.

It's not late blight. The rest of the plant is very healthy with no sign of disease.

I'm stumped!

Hmm. Then I'm stumped.

Have other tomatoes which developed after those also have the same markings?

If so, do they rot on the plant? Or are they just "marked?"
