I am renovating my floorboards in my living room (1930's house) and want to continue them through to my dining room extension (1990's).

The dining room just has board down though - no floorboards. Does anybody know the best way to go about this or where i can buy some original 1930's floorboards from to fit in the diningroom over the board that is already down. I will need them to match the living room boards well as the room continue through.

Thank you.
