To remove the bezel I heated it so the metal would expand with a heat gun. It took about one to two minutes.
When ever banging on the Vespa I look for the softest thing I can find, such as a wooden paint stirrer. The bezel was too snug, due to paint. So I gently tapped the rubber mallet against the wood paint stirrer and it worked great.
Above note: the broken bezel screw and a chip from the paint. This is okay, because the headset is aluminum and will not rust. Plus the bezel will hide it and no one will ever see it.

I need to replace both that screw and the bezel hardware for 1970s headlight assemblies, part number #15221 at ScooterWorks.
The headset assembly was supposed to arrive with a light bulb. It did not. I need one. I used a Sharpie to label what wires plugged into what terminals.
The final items I need for the headset is the terminal for the speedo light bulb as well as the bulb itself.
