The image is a close-up of a brass plate on a green metal surface. The plate is rectangular in shape and has the words "Diesel Engine" and "Ronaldson Bros. & Tippett Ballarat Victoria" engraved on it. Below the text, there is a list of the largest manufacturers of diesel engines in the Southern Hemisphere, H.P.S. 5, and the number "69387". The plate also has the text "800 Type CF" engraved below it. There are also two screws on either side of the plate. The background is blurred, but it appears to be a part of a larger machine or machinery.
