The EKW D-3801 it is!
The type was the mainstay of the Swiss Air Force in WW2 together with the Me109E. The D-3801 was licence built from the MS 406 and developed further mainly by installing a 1000 hp engine instead of the 860 HP one. Further development did not come forward as after the war, Switzerland bought 130 P-51D's surplus in Germany. Only a few years later the jet age started, as Switzerland went to buy De Havilland DH 100 Vampires. etc...
The pictures are from the sole airworthy D-3801 HB-RCF (J-143) operated in Switzerland. The owners went to great lengths to have the cockpit as original as possible. Beside a modern radio and transponder only the altimeter and the g-meter are modern, all other stuff is WW2. The picture Noyade has published, is from some years back.
In this case, Noyade has the lead!
