C-47 Fuel Gauge does bounce and jiggle

Last evening I stumbled on John Wayne flying in ice. I soon realized it was a film version of Ernest Gann's "Island in the Sky", the film name as well.As the flight grew longer and the fuel dwindled, John clicked the fuel gauge-right main, left main. The device jiggled and clicked just as it does in the MAAM simulation. I remember this being challenged and responded to in the manual.Thank you MAAM for such a superb job.Howard
