Wheel alignment

Yesterday I visited the Army Museum at Bandiana and noticed this image in one of the glass cases and was quite intrigued. Apologies for the poor quality of the image. Perhaps one day I can scan it properly rather than shoot it through glass.
It appears to be a F60L undergoing wheel alignment in a special fixture.
I wonder how many pictures there are of CMPs being worked on.
