lap drawer

Photo best description. All wood writing desk.  Top that opens up is two boards hinged together that fold back when open.  Inside desk is small drawer along with 6 cubbyhole shelves.  The wooden writing surface pulls out to use.  There is a lap drawer underneath and two small but deeper drawers, one on each side.  Leg shape can be seen in photo.  Legs are solid and not made for casters.  Only mark I can find is the number 49 incised into the wood in a small area. Don't know anything about the history of this piece or if it is indeed "antique".  Odd looking hinges make me think it is either old or english.
