I can't say enough how happy I am that a 4k version of this film is now preserved for posterity, it doesn't even matter to me if we won't see it. just knowing it exists puts the historian in me at peace.

Mr. Verta this is great work. I don't presently have access to a PC but I'm intrigued by the process you mention of staking sources. I gather that someone could use gimp to align/register images, what do you do to account for the distortion this stacking causes, (ie how do you erase duplicate information but build up more detail?)
