Had what?

Here's the interior of the gatehouse. The brown wheel on the left is used to crank up the portcullis. It turns the large gear which turns a small gear that is connected to the axle with the winch. The differently sized gears make the portcullis go up faster. The grey piece with the yellow tile sits on a pin and is the one-way gear stopper. Pressing it down releases the gear and lets the portcullis go down. Primitive, yet effective.
