You make a good point, but also observe how his mole flips from right to left, depending on the photo. A common problem with Civil War era photographs, is whether or not it's reversed.

The best way I've found is to look at the lock on the rifle most of the subjects are holding. It's a tell-tale of orientation.

Of course some are Daguerre (or ferrotype) and some are glass plate - I should have mentioned that.

In fact, though, it reinforces my point -- no matter WHICH way the pictures are flipped, there just isn't any noticeable facial asymmetry of the sort that indicates actual microsomia.
