What is this USAF transport aircraft from possibly the 50-60s?

It is indeed a C-130A. The large tail numbers indicate it's from the late 50's or early 60's. In the late 60's, the USAF went with smaller numbers forward of the passenger door. Here's a similar a/c ...

How is it possible that the design criteria for turbulence intensity has nearly doubled, but the manoeuvring load factor is the same?

Turbulence intensity applies to the air around the aircraft. The sustained load factor applies to the aircraft itself. These are apples and oranges, one cannot be directly compared to the other. In a ...

In big transport jets, what is the difference between manoeuvring loads and gust loads?

Manoeuvring loads are well defined, controlled and regulated. The (auto-)pilot induces them, and the quasi-static loads can therefore be fully controlled. Gust loads are sudden impulse loads, ...

Without the M, people would simply confuse the military cargo plane with the civil airliners that Airbus builds (e.g. A320, A380, etc).

How is it possible that the design criteria for turbulence intensity has nearly doubled, but the manoeuvring load factor is the same?

My question boils down to: how an aircraft can withstand very high momentary forces but not very high sustained forces. From your question one can gather the maximum manuvering load factor has ...
