The Russians knew the Germans better than anyone and here is what they have to say about the Bf-109
" In early 1939, "Messerschmitt" proposed carrier-based fighter Bf 109T ("Trager" - carrier-based). By design, it was close Bf 109E, had an increased wing area and sweep on each console was more than 0.6 meters Here are elongated slats and ailerons and flaps had a large area. Between the fifth and sixth frames fuselage attachment point was to catapult. Planting hook was attached directly to the seventh frames. The design of this place has been strengthened for the perception of large loads. Wings could be folded by hand directly on the hinge mounts for nodes guns. Overall width with reduced up to 4.1 m, however, folding wings was quite a complex operation, as previously required to disconnect the flaps. Armament consisted of two synchronous MG 17 machine guns, and on the wings could be mounted either two MG 17 machine guns or two guns MG FF. Bf 109T was adopted, but a detailed study of the project was transferred to the "Fieseler". At the same time directly to the assembly line began reworking 10 Bf 109E-1 in pre-production Bf 109T-0, and "Fieseler" received an order for 60 Bf 109T-1.
Bf 109T-0 engines powered DB 601A, to increase the glide angle on the upper surface of the wing spoilers were installed, and the landing gear were strengthened. After testing in Travemünde winter 1939-40 they were intended to convey to military trials in II / JG 186 (kernel which were 5th and 6th aircraft carrier fighter squadrons). However, work on the "Graf Zeppelin" in October 1939 to a halt, as they found the use of one aircraft carrier away from bases impractical. Finally, the work was stopped in May 1940 II / JG 186, meanwhile, came in as the third team in the JG 77 and participated in the French company. In June 1940, the group moved to Trondheim in Horvegii, and on June 6, it was renamed in the III / JG 77. Assembling 60 Bf 109T-1 on "Fieseler" stopped immediately after the suspension of work on the aircraft carrier. But the success of the British aircraft carrier in the Mediterranean Sea at the end of 1940, has attracted renewed interest in this type of ships. Although immediately begin work on an aircraft carrier was considered premature (they resumed May 13, 1942 g), "Fieseler" was ordered to complete 60 Bf 109T, but without carrier-based equipment. The plane was made in the fighter-bomber version, adapted for use with short runways."
By the way the Germans did some testing, but I have never seen a picture of the Bf-109, attached is one of a Bk-534
