It can be 'finish ready', which means machinging, planing then applying finish, rather than machining, sanding, finishing (which raises the fibres of the timber as they are abraded, rather than cut), sanding, refinishing, etc. Tends to reduce the chance of splinters too, as far as I know.
It's Horween. It's stamped the same way regular scotchgrain calf is. Ron has commented he could probably source more if he wanted to, although how that would hold up with the 'shell shortage' I don't know.
