We have a one room schoolhouse on our farm in Northern Missouri. The wood floor was removed approximately 60 years ago, the school was moved and put on a concrete slab foundation. My wife and I would like to restore the schoolhouse. We have a lot of questions that I hope someone can help us with as follows:

1. Do you know any resources on tips for restoring one room schoolhouses?
2. Do you have any suggestions on where to find one room schoolhouse artifacts and furnishings?
3. We have narrow board oak flooring manufactured by Eastman Gardiner & Company that either came from this schoolhouse or another one my grandfather tore down. Does anyone have any tips on how to re-use old oak flooring?
4. Since the schoolhouse currently has a concrete slab foundation; and since the plate is approximately 8 inches thick; we were considering putting down floor joists, a sub floor, then re-using this oak flooring. How do we keep moisture and mold from developing between the concrete slab and the sub floor?
