First 109 K4 ever to be restored

[Richie]

Stuff I found.

The Bf 109 K-4 was the fastest 109 of World War II, reaching 710 km/h (440 mph) at 7,500 m (24,610 ft) altitude[101]; improved propellers were being developed when the war ended which would have boosted the speed to 727 km/h (452 mph), and 741 km/h (459 mph) was expected with an experimental swept-back propeller design.


It doesn't go like that in IL-2
