Wow!
What was the history of the place? How old? Find any other cool stuff under it? In the walls?
We did the exact opposite of what you did, some people call it remodelling... hahah
In our case when some flooring came up we found 1920 newspaper prints on the wood floors. They had not been finished, only around the edges, and the ink had transferred the print image to the floor.
We got a lot of oak out of some parts of the house. it was difficult, tedious, time-consuming work salvaging that stuff. So, nice job or your part.
Those iron cut nails make for interesting decor, we have plans for shadow boxes with some of the other circa 1900 metal, pulleys, and what not found at our place.
Find any coins? Did you run a metal detector through it yet? You should!
How about the banister on the stairs? Usually back in those days the stairs were the best, heaviest wood available.
Man, that is a lot of work.
