I am trying to build up a mode-matching model for the SQZ to OMC path. Measured the height of periscope closest to -X Side in SQZT7.
Height of periscope base plate measured 5/8 in. D1201011 front plate reported 25 in tall in design documentation.
Top of D1201011 to center of upper periscope mirror measured approx. 63/64 in.

Vertical beam travel in periscope thus computed as 22.61 in (574.3 mm).

Images of ruler measurements are attached.
