Reinstall the Ocular Slide Assembly (Left)
Carefully place the left-hand ocular slide assembly into
position on the front frame, making sure the lower
beveled edge seats into the beveled dovetail channel in
the bottom of the frame (see
Figure 94 ), and that the
index pin in the index arm engages with the lower slot
in the brass pivot lever (see
Figure 95 ). Be extremely
careful during this process to neither scratch nor
smudge the P6 prism in the process.
