"That's right, Jay!"
As he just said, we were initially using the LD as a reference, but then got our hands on a copy of a tv broadcast. This master apparently came from a Umatic and, surprisingly, looks better than the LD. Both seem to come from the same telecine.
Here's an example. LD on top, TV master below:
Notice how the LD looks blown out and in general seems to resolve less lines.
Interestingly, when this scene was localized, it appears a clean plate of the shot wasn't available, so the camera pan actually stops earlier, before the english text is supposed to appear, and the italian text appears on a freeze frame. As you can see, the door isn't in the center of the shot.
Here's a couple more screengrabs, to give an idea of what the rest looks like:
Now, I've run several comparisons, first with the LD and now with this new master, but both sources seem to indicate one thing: the typeface used for these italian titles does belong to the same family as the typeface used in the original title cards, but it is in a different weight. In other words, I've found an exact replica (or really close to it) of the original font used for the movie, and it doesn't match with this one. Like, at all. At first I thought the LD being blown out might account for it. Nope, different weight. So I've been burning my retinas lately trying to make a custom font.
For further reference, here's all the title cards
