How to date a wood floor?
I have wood floors throughout my home. I am almost positive they are not original to the house (built in 1857) because they don't match the staircase and are in such good shape. I'd like to be able to date them, but I'm not sure if that's possible. POs are no help, unfortunately.
The living and dining room floors are laid out in a pattern of receding squares. The boards are laid out in the shape of a square and go inward until you get to the very middle of the room, where there's a square of about 4" x 4". None of the other rooms have patterns, and there's no inlay anywhere. I'm afraid I don't know what kind of wood it's made of.
I'm attaching a photo so you can get an idea of the color of the wood (if that matters?) and the way the floorboards are laid out. Is it possible to get an idea of the floor's date from just its appearance, or is this an impossible task?
