I found some more Motion I from November 1969...
And then I found this one. If, in fact, the pro photographer captured everything from the wrong side of the car, then this may be the only one from the right side during the test runs. However, there's still hope. These were from a roll of Kodachrome Transparency, processed NOV69H2 and are slide numbers 6, 7, and 16. So there are still a lot of photos from this roll that are missing. My guess is that Alex would have given them to whoever was his primary contact on the team.
If you look at the numbers on the car, everything looks smeared at a 45 degree angle. I don't think the yarn was headed at that angle. So, if someone has a good way to eliminate that smearring effect, copy this pic and do what you can. You can still see the angles that the yarn is headed in as it would have been originally if you just look at each individual piece and mentally subtract out the smear. It looks to me that there is still some incredible information captured in this photo...
