One small issue, very anal and probably not even accurate - isn't the film title normally justified to the left on ratings cards?

Yes & No. As I said above, "the card went through a number of design changes in the 90's..." The left aligned (re-designed) card came after this one.

I do have a HQ raw scan of this card but haven't ever needed it so it isn't properly formatted as per the older card in my last post.

Just out of interest, what's the font used on the 'Only for persons...' part? That would need editing if other certificates were used (and that text layer seems to be rasterised).

That font (in Gimp at least) is white (#ffffff) 'Times New Roman' regular at 69px, and -0.2px character spacing. It would likely be the same in photoshop.
