While I don't know anything specific about Allison Engine tools, I do know that aircraft engine designers of that era were known for including custom fasteners and adjusting mechanisms in their engines that required special tools.
One theory is that the engineers were stretching their capacities to get the desired performance. Another is that they wanted to make their designs unique ("cool") so they embellished them with these details.
Then again, perhaps the special tool requirement was to keep unauthorized persons from tinkering with things they had no business touching.

I have to agree with your thinking. Looks like the wide head ratchet will fit, but not together with the breaker bar.
