I'm posting this again because it has still not been identified. Could
this be the first aviation item to baffle the gurus in this NG??

From the previous thread I think we would have to agree that it is
not a glider, or a relatively high performance fighter type of that
era, or a chopper (wrong instruments). Also, I think it would have
to be single pilot and probably single engine. I know it is not a
Link Trainer - were there any other "simulators" around then? The
instruments are of American manufacture and they were last overhauled
by Kingsford Smith Aviation, Bankstown (Sydney, NSW) in 1969.

Any further ideas?

The airspeed goes to 300, say mph, but the altimeter only to 2000 feet?
