Can the image even be properly IVTC'ed? The problem is that this was done on the older kind of telecine which used pickup tubes. The lag in the tubes caused moving objects to smear, especially light objects over a dark background.

I don't know if there is any clear 3:2 pattern like the later flying-spot systems which did pick up discrete frames. I can't really figure out how the pulldown system worked on the older process - from watching old transfers like these, it seems like even if you were to pull the fields apart, they'd still contain the picture info from adjacent frames smeared together.

I barely even know what I'm talking about here...maybe someone else knows more?
