I noticed that orange peel texture in the first pics. It's often associated with Vacor. But you also see it on some big old Akros, like Claudias and Jolly Rogers, where it adds an interesting dimension to the marble. It's usually considered a flaw that is associated with poorly made marbles (the big Akros are all dug, as far as I know, and the surface texture may be why they were discarded, but I actually like the effect on those marbles).
