Description Combined window, doorblind and awning made up of a wooden frame composed of four equivalent posts with a flatter wooden piece joining them at the top, fitted into a wooden platform at the other end. All of the wood has been coated red. There is also a steel rod that passes through each wooden beam toward their tops. the rod is held in place by four steel strips (each running down a separate wooden beam) with two screws going through, attaching each to one of the wooden beams. Connected to this metal rod are four brass ringlets with twine tied around them. Each individual piece of twine is connected to its own shutter below by a metal ring that is halfway down the shutter.

Five metal shutter blinds are connected by a metal rod toward the top of the wooden frame and extend to the platform below. A hand crank is connected to gears at the top of the frame, which spins the pieces of twine around the brass wrap-arounds on the metal rod, raising or lowering the shutters, depending on their initial placement.

There is a steel awning overtop of the five thin steel shutters. All of this metal and the four metal pieces that join the turnable metal rod to the four wooden beams are coated green. There are also three metal latches on the wooden base of the object, which appear to fasten into the metal shutters in order to lock them in place. There is also paper markers attached by string that includes the model's patent number, inventor, patent title, and patent date.
Notes Combined Window, Door-Blind and Awning, based on patent no. 74399, which was invented by G.M. McMahan of Mount Sterling, Kentucky. McMahan's design was patented February 11,1868.
