The Bf-109F had three different types of seats throughout its development. One being the early style similar to the style of seat in the Emil but completely different. It was more representative of the style of seat used in the Bf-110. Then the seat moved towards what we are familiar with but with a different backplate. This was short lived and the familiar backplate that would be in the Gustav was the final version.
With the release of the Bf-109F-2 from Eduard, they have added this early style of seat. Some of the most famous aircraft, such as Galland and Molders, have the early style of seat.
