This Amerock Knob seems to be a better collection of Hobby Parts than it is a complete knob. Take a look her. First, there is a modern mounting ferrule and screw for Glass Knobs. Or maybe a base for your own knob design, or use four of them and make a set of axles and wheels for a toy. Please note the very high tech and meticulous drawing illustrating the measurements.
