I have HW floors from the 1960's that are in good shape, except for one room
which I plan to sand. Can anyone suggest a stain to match the photo in the
link below? I believe it is white oak, not red. I was thinking of first
starting with a "Natural" stain, but am wondering if that will be dark
enough.

Thanks for any help.

Try Colonial Maple, and maybe some golden oak mix.
This floor you are showing is Natural, just aged poly.
