OK, johnrt, I hope this all makes sense.
I placed a piece of blue tape on the visible edge of the control panel next to the lower bezel mount to represent the visible edge:

Then I pulled out the CP a little and measured the portion of the panel that is tucked under the lower bezel groove: 12mm

Then I placed the ruler across the entire visible area like seen here:

...and zooming into the front edge. The total visible area comes out to: 197mm (you will notice this measurement does not include the t-molding on purpose)

I also placed the ruler on my reproduction CP (Identical to my original CP by the way) to measure the total height of the control panel:

...and zoomed in the measurement of the entire height of the control panel is almost exactly: 210mm

I also screwed in my crappy CPO and measured the wider top edge. (Distance from the top edge of the CPO to the edge of the CP tucked under the lower bezel): 20.22mm

And here is the meassurement of the opposite side. (Distance from the bottom edge of the CPO to the edge of the CP with t-molding): 15.63mm

And in case you need it here is the distance from the left/right side of the CPO to the edge of the CP: 8.53mm

Hope this helps. Glad to take any other measurements you need.
