The Bf-109K-4 was the last completely-new version of Messerschmitt’s famous fighter to achieve operational status before the end of the war. While the Bf-109G-10 came to the units of the Jagdwaffe after the Kurfurst, one should remember that the G-10 was largely the result of remanufacturing Bf-109G airframes in order to achieve a production standard that had become hopelessly diverse with all the sub-types in production.
