I guess you gents are all on the right side of the pond? While equipped slightly differently, the above panel is a distinct part of the cockpit.
For the first 4 years of production, these instruments were additional cost upgrades. The panel they sit in could be blank, one hole in the center or two holes. The compass cost 15.63 and the airspeed 20.00. Oh, yes, an appropriate panel cost .37.
