Strange mix of English language and German gauges and placards. Who knows what's authentic to the 1930s/40s?

None of the gauges looks to be authentic. In fact, the entire instrument panel might be a replacement.

My guess is that the black and silver placards riveted to the throttle quadrant, and what I take to be the engine flaps or prop controls and the magnetos, are authentic, but that section of the photo is out of focus.

Links = Left
Alle = All
Rechts = Right

Auf = Open
Zu = Closed

Schmierstoff Kühler = oil (literally "lubricant") cooler/radiator.

Druck??merven. . . = Pressure???
