Could it be that the army was saving money by using the unvented spines for mounted troops?

Eh? Not sure if I understand? Well, actually...I am sure...I don't understand what you mean?

So you are referring to private purchase then Joe? Government purchased helmets bought in bulk under contract for issue would be made as per the Probe supplied to the manufacturer; private purchase helmets could be bought in the levels you show above in different materials.
Personally, I try myself to avoid making generalizations based on catalogues.
