The Bf-110F was a transitional aircraft. It was put in place with the failure of the Me-210. It was an interim until the G-2 could be produced in numbers. Only 500 were made, divided between night fighters and fighter bombers.
Interestingly, Eduard elected to release the F as a weekend edition. This is the first time that the Bf-110F has been available in any scale that I know of. This cardboard box is so jam-packed with plastic it is surprising to me that it costs so little. Because of the transitional status of the real aircraft, it had features of the older E model and the newer still-to-come G model. Eduard’s parts break down shows this transitional parts listing, necessitating the parts from each of the earlier releases. There are a lot of extra parts because of it, even extra fuselage halves.
