Spark plug tester: Does anyone know how to use this tool?

This has been sitting in my garage for a while and I came across it today and pondered it's use.
It's got a crude feeler gauge on it, the fil e's use is obvious, and there's another bit that bends the plug terminal.
Here is a pic:
Looking at the top of it there is a copper bit protruding through the plastic molding and there's a small globe in the middle of it.
How do you use it?
And what does the bit on the very left do? It's flat, uniform thickness (maybe 2mm) and chromed.
