Rolltop Desk age?

I have this roll top desk and was wondering if anyone knows the carving and maybe how old it is? I hope the picture comes out. This picture is of the back side of a roll out chair that goes with the desk. The drawer fronts have the same type of carving. It is quite large, 60 inch wide, 57 inch high, 25 inch deep. moving this is quite easy, the desk comes apart in to 4 pieces.
There are a set of drawers on one side and the other side was a safe cut out and one drawer. The center piece is glass and I have a piece of wood that can be used. The top all 60 inches left off the drawers. Any help is welcome.
