I would expect BAV99 dual diode for some kind of clamping to rail. Not sure as it would require a bit more reverse engineering.

A 3.5 digit 4.5 digit 5 digit 5.5 digit 6.5 digit 7.5 digit DMM is good enough for most people.

I also have a Fluke 79III and opened it up. This is what the parts in my device look like, maybe this will help you.
