The image shows an old-fashioned blackstone oil engine, which is a type of steam engine used by Patrick Leonard. The engine is mounted on a wooden frame with two large wheels on either side. The wheels are made of metal and appear to be old and weathered. In the center of the frame, there is a black sign with white text that reads "The Blackstone Oil Engine Shipped to Arno Bay about 1900" and "Patrick Leonard." The sign is attached to the frame with a metal bracket. The background of the image shows a workshop or garage with various tools and equipment hanging on the walls.
