My fiance and I have recently purchased a house and I'm having problems finding an answer to my question. Our front entry door has the door knob in the center of the door instead of on the right side like standard American homes. I would like to replace the door knob but I'm not sure if it's a special knob or if it's a standard knob. I'm hesitant about taking it apart to find out because if it is something special and I take it apart and it won't go back together I don't want to be stuck without a door knob. I would also like to know if anyone would know where to find the latch mechanism that goes inside the door. Obviously it's going to be longer or be a different setup than a regular door. It's not the main lock on the door, we have a deadbolt, but I would like to update the handle if possible. We don't want to replace the door because it's unique and quite the conversaton piece. Any help or advice would be much appreciated. I've searched all over the place and only found pictures of these doors but no information on them.
