This shot was on the same page as the LM wheel, along with photos of wheels from a few other ZAZ Museum residents.
I also found this blurry postage-stamp-sized shot of what I would guess is the other white F1 - Okamoto's #031 - on track. This photo was linked from an even smaller thumbnail if you can believe that (gotta love those tiny images on Japanese websites

) and I literally laughed out loud when I clicked on it and
THIS was the "larger" version.
