School desk model but this desk does not have a patent number or patent tags so it may be a salesman's sample. The three desks are lined up front to back giving an indication as to what a free standing front desk and a free standing back seat will look like and why it is necessary to order one of each of these per classroom row. Two have chairs attached to the front and the last has a separate chair. There is an enclosed shelf under each desktop. The legs of desks and chair and supports for chairback are metal and all are screwed to a mahogany wood base. The middle desk and chair is missing one screw on one support on the same side.
