Nice diagrams, actually the earliest 2-oz trigger was one not shown built by Hart for Remington and very similar to the trigger Hart builds today with adj. LOP. The above 2-oz came out in 1961. What year is your rifle? After ~ 1964 the 2-oz looked like Freds diagram.
The trigger pictured looks like the 722/721 trigger and not 2-oz.
