[Leica] 135mm f2.8 'eyes' adjustment

[leica@davidmorton.org]

I have here a borrowed 135mm f2.8 with the 'eyes'. The problem is that when
you fit it to an M body with good vertical v/f alignment, the two images are
out vertically.

This happens on all of my M bodies, even though those bodies have perfect
vertical v/f alignment, so the problem is clearly in the 'eyes' of the 135.

There are six screws on the back of the rectangular side, and three on the
round side. Does anyone know if any of these are adjusting screws, and if
not which of them let you gain access to the adjustment that must be hidden
inside?
