Crimpers
Middle one looks like another GM open barrel crimper now made by Sargent.
Sargent may have bought out another tool manufacturer so may not have been the maker of the originals; or maybe they are - they've been around long enough.

Crimps the conductor and insulation in two seperate steps. Supposedly for 22 to 12 gage 56, 58, 59 Series Packard terminals and similar.
Came across these on Mouser and Sargent's website when looking for a crimper made for 10 and even 8 gage wire for ring terminals. (nothing to report on that front).
