A few strange things...
The Manifold Pressure gauge in the last pic is marked “2” meaning a multi engined aircraft. However the gauge in the other pic before is not so marked. I’m assuming it is a single engined aircraft, using a gash MP Gauge.
The speed limitations are placarded in MPH but the ASI is calibrated in knots. Surely not good practice?
VC (max cruise speed) is placarded as 270 MPH but the speed on the ASI (top of the green arc) is 280 Knots. A big difference....Is that right or have I got something wrong here?
So is it a high performance, single engine, American, Warbird type and tail wheel judging by the nose up attitude?
