The image shows a close-up of a metal object, which appears to be a part of a machine or machinery. The object is displayed in a glass case with a beige background. On the left side of the image, there is a small blue tag with the number 1861 written on it. The tag is attached to the top left corner of the object with a screw and a bolt. On top of the tag, there are two metal clamps, one on each side, which are used to hold the object in place while it is being held in place. The clamps are silver in color and have a curved shape with a pointed end. The body of the machine is made of metal and has a circular dial in the center. The dial has a small hole in the middle, which is likely used to adjust the angle of the clamp.
