WTB 35mm Q-60K and Q-60E targets for scanner cal

If you are done with your 35mm slide scanning project, perhaps you would like to part with your scanner calibration targets?

I am starting to scan many Kodachrome and Ektachrome slides from the 1960s & 1970s with my Nikon CoolScan 5000 and VueScan. I would like to calibrate the process with IT8 targets in 35mm such as the Q-60K and Q-60E.

I also could use a Nikon CoolScan 8000 or 9000 for larger format with larger format IT8 targets and would consider a package deal.
