I took some additional images of the smaller spinner of the internals.
Given that the front is all smashed in, it is hard to tell what type or size hole there is at the tip of the spinner, although you can see the rolled over edge from these images.
There is also no slot or access hole as per the RED spinner to allow access for tooling to remove / tighten the spinner.
A friend I know who works on restoring Luftwaffe aircraft initially said he thought it looked like it was from a fighter, but he followed that up with another email by saying that he was unsure what type.
Well, the waters are a little less muddy than when I started, but to be able to say definitively that it was used on this or that type of aircraft would be great.
