Based on the checking pattern, the sharp shoulder pair are from 1946-1952. But, there is no divot for the round head screw, so this pair is from the latter half of that period.

The tapered shoulder K frame set is from the 1953- c. 1967 period. After that, the diamond disappears.

The N frame pair is also quite early. Not only is the shoulder sharp, but you can see the divot for the round head screw.
Thanks for answering the question about the change from early to late shoulder, I had asked in another thread
