Two more images from the IB TECH.

I need to get back to the seller, is there any interest in securing this?

If funds could be raised to secure the print, I can scan it @ 4K.

We could then register the print to the BD using Elastix, and take the chroma from the print, and apply it to the BD.

Alternatively we can use the 'match grade' function in Nuke or Resolve to pretty much automatically grade the BD to match the print, then just touch up any tricky bits.

The print can be sold when the project is done, so at least a reasonable portion of the money would be recouped.
