Questions about some Files in the Backend

[Phil of Loreauville]

I was digging around in the mod data files and I've noticed there are some references to units I've never seen nor can I find any mention of them in any of the export_descr_buildins.txt file.
Like in the ui/unit_info folder for England there are images for Norman Archers and Norman Crossbowmen but I can't find any references to them in the mod data files. Furthermore there is an image for Gendarmes in England but, if I'm reading the files right, those are not available to England.
Am I missing something?

They might be left over from an earlier version of SS.
