Alternator voltage regulator teardown and analysis

I am only saying- I believe there is a certain inconsistency in the components or manufacturing process that could be fine tuned. Always appreciate your input.
Actually someone aftermarket DOES make them. And you could "used to " buy the heavy duty one from 69/ earlier.

Here's one for 70/ later

This was the old one, also sold by Standard / Blue Streak. We used to stock them
