Sorry Guys. Duff information. The publication from which I obtained the photograph is wrong. I have found the same photograph in another publication on the Focke-Wulf Ta 154:-
Here it is entitled
"A mock-up of pilot's cockpit of Ta 154 V1 prototype". This seems to be more likely. Which only goes to prove never believe everything published.
Apparently the word written on the panel is Schusszahler which translated means Shot counter.
