This a view of the castings from the Ted Young hit and miss, plus a finished engine. I didn't take this photo and cannot account for the color of the castings - it must have been lighting? Maybe Ted cast some in bronze, that I can't verify. In April 2008 I purchased a set of these castings and traded them off to a friend of mine. Mine were cast iron ... and I believe these are the same. See the next photo for another finished engine and some dimensions.
