If someone could post the corresponding frames from the existing scan, that would be great as I can see wether it is worthwhile recleaning and scanning the print myself.

These are from a quick test-scan I did this morning.

These have been quickly resized and the saturation boosted slightly, I haven't attempted a full colour restoration/grade.

I'm hoping that the better scanning equipment and technique is getting better results than the scan done in the US.
