[I]Why the ambitious (accelerometer?) for a low speed non aerobatic aircraft. Must be a clue to its role here.[/I]
I do not wish to mislead you but the aircraft, that I think this is, was not designed as an areobatic aircraft.
Also intrigued by the great lump of (non magnetic I hope) metal next to the compass.
The panel that matches this panel is identical except for a few differences and certainly does not have the large silver coloured "lever" you are referring to.
The Throttle and Mixture controls look 60's Cessna... RR Continental Powered?
The engine of the version I think this is did have a Contnental engine.
Is this a prototype?
I do not think that this is the prototype but it has had modifictions to the original aircraft I am sure.
I am basing these answers on the aircraft I believe it is, I do not wish to give the answer but give others a chance. I am 99% certain I know the aircraft.
