Fluted firing pin conversion

Interesting pictures, and conversion. I have a couple questions, just to satisfy my curiosity...

- The pics are too faint to see machine/tool marks - the flutes are milled, not ground?

- It's generally accepted that this was a cheaper/easier conversion than gas ports in the breechblock (like Borchardt C93)?

- I pulled out my 1937 S/42 to check and see how far the flutes extended on a 'factory' flute, but the S/42 firing pin has no flutes...In fact, it has no markings at all...How did the conversion flute compare to the 'factory' flute in width, depth, and length???

Milling machines (and grinding machines) are not something you would see even at depot level...How ere the converted firing pins done? Send in the entire pistol, or just exchange firing pins? Wait until pistol needed rebuild or send in when change was posted?
