This is the rocker arm for the Webster. You're basically viewing it in same (top) view as that drawing but because it's a real object and not just one view, you see part of the front of it. I put a 4-40 Socket Head Cap Screw in the tapped 4-40 hole on the right just because. Although that does make it look a little wonky.
The notes you see that are handwritten are derived dimensions, usually to tell me where to place my cutter for different features. You'll see they're all 0.250" from a feature - a sure sign I was using a 1/2" diameter end mill and had to specify start and end points for tool movements.
