Perhaps two pilot seats but modified & joined later?
I don't see any "asymmetric top contour".
The reason the top of one of the seats appears slightly higher is simply that the other seat is missing a back leg (you can just discern the bracket to which it would have been bolted in photo #6) and is therefore tilted back a bit more.
