This is a reproduction cabinet, it is not old, it is just made out of old doors.
This does have a couple of issues: the shelve are not as deep as the cabinet itself, so there is space between the shelf and the door, the bottom left corner of the door sticks out a little (it had a mind of its own, I couldn't get it to stay in) and the backing is 3 pieces pieced together. There is a lot of character in this piece.
