The image shows a display case with various items on it. On the left side of the display case, there is a large red wheel with a hook attached to it. The wheel appears to be made of metal and has a label on it that reads "London". On the right side, there are two smaller red wheels attached to the top of the wheel. In the center of the image, there seems to be a small metal box with a clock on it, which is likely used to measure the pressure or pressure of a machine. The box is mounted on a white wall and there are several other items on the shelf below it, including a green gas cylinder and a wooden bucket. There is also a framed picture hanging on the wall in the background.
