I think after boiling red oak bark, the liquor was used to contract the skin. What chemical is unique to red bark, I don't know, but I believe it had Native-American uses, and that's probably where it was learned.

Tannins, from which the word "tanning" comes, are plentiful in oak bark. As far as I know there's no reason it should be red oak particularly - they probably picked a common tree near Richmond.
I had a friend who experimented with home tanning using bark and it does work, although the resulting leather was stiff as all get out.
I've skinned a squirrel once and let me assure your that a couple of them stitched together will make nice indoor slippers, but I wouldn't want those thin skins for moccasins. They're too thin and will wear out quickly.
A lot of nuts and berries provided many colors for the leather. Last year while trying to husk some black walnuts I found out the hard way. My hands were still stained for a week after many many washing. Soap, gas or you name it had no effect.
