Messerschmitt Bf-109F
The work of Willy Messerschmitt and Walter Rethela it was a pioneer of construction, utilising the latest innovations in metal technology and aerodynamics. It along with the Spitfire ushered in a new era in fighter plane design. It represented a continuation of the process of man's conquest of the air.
The Me-109 was developed in 1933 following on from the fighters Heinkel He-51 and Arado Ar-68. Along with the Arado Ar-80, Focke Wulf Fw-159 and Heinkel He-112 it formed the basis of the Luftwaffe fighter arm. By 1936 there existed several versions of the Bf-109 and modifications (A, B-0, C, D and E). They took an active part in the Spanish Civil War of 1936-1939. A number were adapted for aircraft carrier use (version Bf-109T - these aircraft were destined for the never completed carrier "Graf Zeppelin" and were assigned to combat unit JG 77). At the onset of WWII Me Bf-109 in versions B, C, D and E were used in the September campaigns in Poland, Norway, Denmark, Holland, Belgium and France. The defensive fighters of these countries (French Dewoitine D-520C-1, Curtiss Hawk H-75, even the English Hawker Hurricane Mk. I of the British Expeditionary Force in France) were no match for the Bf-109. Utilising the tactics learned from the Spanish war paid off in excellent results and victories.
However in the Battle of Britain the Luftwaffe suffered defeat. The reason for this was largely the Spitfire and RADAR. At the time of the appearance of the Spitfire, the Me Bf-109E was an old version. At the beginning of 1939 a new version, Bf-109F, was fitted with the new Daimler Benz DB 601 engine and with new armament (Mauser MG 151 cannon of 15mm and two MG 17 machine guns). Likewise the aerodynamics were improved (new engine cowling, new propeller and spinner, new wings, etc.). The new version started to be supplied to units at the end of 1940. Version F took part on all fronts in WWII (in Europe and Africa) except for Asia. It was supplied to Czech, Spanish, Slovakian, Hungarian and Italian squadrons. Those who flew these planes and excelled included Adolf Galland and Hans-Joachim Marseille.
The end of the war saw the production of versions G, H, K of this excellent plane. Production took place in Germany, Switzerland (E), Spain (versions G and HA 1109-1112 with various engines including the famous Rolls Royce Merlin 500-45 - planes were made in Spain until 1958) and Czechoslovakia which produced the Me Bf-109G under the name Avia C-10(S-99 and trainer CS-99), and later with a new engine (Junkers Jumo 211F) as the Avia C-210(S-199 and CS-199) "Mazek". Also 25 planes were delivered to Israel in 1948.

Supermarine Spitfire Mk. VB
One of the most renowned airplanes of the Second World War - the English Spitfire was designed at Supermarine by the designer renowned in the thirties for his record-breaking seaplanes - the engineer Reginald J. Mitchel. The prototype denoted 300 was demonstrated on the 5 March 1936 and met expectations. It demonstrated high speed, good turning ability and easy handling. In 1937 the Spitfire Mk. 1 enterred production armed with 4 machine guns of 7.7 mm calibre. A new producer (castle Bromwith) signed a contract to produce 1000 planes. By the end of October 1939, a total of 4000 Spitfires had been ordered. One of these planes was ordered by Poland in 1939 for assessment and comparison. The plane was sent to Poland in August 1939 via Roumania although this route was unplanned (serial number of the unit was 281 - RAF L1066, it was sold together with 10 Hawker Hurricanes and 100 Fairey Battle bombers, none however reached Poland - those interested in the story of the "Polish Spitfire" can refer to the article "Spitfire over Poland" by W. Matusiaka in Aeroplan 1/96). From unit 175 the more efficient Merlin III engine was fitted as well as a three bladed propeller with variable pitch. Also during production an "armoured" windscreen and front cockpit shield was fitted together with a steel plate to protect the pilot from the rear. Two types of the Mk.1 version were made - Mk. 1A armed with eight 7.7 mm machine guns and Mk. 1B with two 20 mm cannon and four 7.7 mm MG's. Altogether 1566 Mk. 1 Spitfires were produced. In 1940 Mk. II appeared with the Merlin XII of 864 kW (1175 horsepower) and a three-bladed metal propeller with variable pitch. Likewise there were type A and B of Mk. II - 920 examples were produced.
At the beginning of 1941 production was started of Mk. V. They differred from previous versions by having a reinforced cockpit and engine compartment, thicker armour, and propulsion by a Merlin 45 of 1080 kW power (1470 horsepower). There were three types: like version Mk. II A and B, as well as C (armed with 8 MG's or 2 cannon and 4 MG's). A fighter bomber Mk. VC was produced, and by 1943 all versions had attachments for bombs: one 226 kG bomb under the fuselage or two 113 kG bombs under the wings. In 1943 a version of the Spifire was built (LF Mk. VB) with cut-off wing tips to achieve higher speed at low altitude. Spitfires were delivered to English fighter squadrons from June 1938. Mk. V appeared in fighter squadrons in March 1941. Likewise the Spifire was supplied to Squadrons of the Polish Air Force in Great Britain. At the beginning of 1941 Spitfires were delivered to squadrons 303 and 308, and to the remaining fighter squadrons except 317 by the second half of 1941. A Mk. V was in Polish squadron 303 by June 1941 and by August in the rest of the squadrons. It is this version Mk. VB which is made using this kit. Furthermore, from July to August 1943 all squadrons except 318 were equipped with Mk. VC, and squadrons 303, 306 and 316 had also some Spitfires LF Mk. VB.
The Spitfire was a single-seater fighter, metal sheathed, with retractable undercarriage, propelled in Version V by a 12 cylinder Rolls-Royce Merlin 45 engine with a power of 1080 kW (1470 horsepower); armed with two 20mm Oerlikon cannon and four 7.7mm Colt Browning machine guns, one 226 kG bomb or two 113 kG bombs; among other equipment: ultrashortwave radio type TR 1143 and radio identification equipment IFF (Identify Friend or Foe).

Construction of "Spitfire" Mk-Vb
General Comments
1) Before assembly it is advisable to carefully aquaint yourself with the overall plan and the assembly diagrams.
2) Each assembly sketch comprises a module to assemble with complete enumeration of the parts needed for its completion.
3) Parts marked with the letter "P" (prawa=right) are assembled similarly to the parts for the opposite side marked with "L" (lewa=left). (NB the designer seems to be dyslexic as often the P and L are on the wrong side!!)
4) Glue parts marked with an asterisk * (and those printed on thin paper) to cardboard of 0.5-0.8 mm thickness.
5) Before gluing together the fuselage segments take special care of the symmetry of the structure.
6) Adapt parts if necessary after dry fitting without glue.
7) Wire of assorted thickness is shaped according to the provided full-size templates.

Construction is started by gluing together the fuselage as shown in assembly sketches 1, 2, and 3. The fuselage consists of 8 segments and the vertical tail fin and rudder assembly.
Segment 1 - shape parts 1, 1a, 1b, 1c and 1d and assemble by gluing behind the edges tabs 1f, 1g, 1h and 1j. Glue in place frame 1w'. Construct framework using parts 1p and 1r as well as frames 1s, 1t, 1u, and 1w as shown in assembly diag. 2, this is glued inside to give the segment its proper shape. Glue in frame 1z. The upper segment covering is made from parts 1e, 1kP and 1kL by shaping and then using gluing tabs 1LP, 1LL, 1mP, 1mL, 1nP and1nL as in assembly diag. 2. Glue the completed unit onto the framework and skin of the segment. (Diags. 1 and 2).

Segments 5, 6 and 7 - form and glue together the parts according to diag. 1.
Segment 8 - form out of part 8 and attach tab 8a to this. Glue frame 8b in place. Assemble framework using parts 8c, 8d and 8f, and glue inside the segment to give it its correct shape.
Vertical tail fin - make from parts 9P and 9L, reinforcing with tab 9c, curve accurately to shape and glue tab 9a. The finished unit is slid over the framework and tabs of the segment and glued into place as shown in assembly diags. 1 and 2.
Cut out the slots in segment 8, insert the spar 10c through these and glue parts 10d in place. Next shape the stabiliser sheaths 10P, 10aP, 10L, 10aL and glue together using tabs 10bP, 10bL, 10eP and 10eL. Glue the units to the fuselage, strut and parts 10d as per diag. 4. Glue the fairings 10eP and 10eL as in diag. 2.
Wings - construct the supporting framework and shape and glue the covering sheath from parts indicated in assembly diagram 5. (Start with part 11c - parts 11-11b are used later).
Attaching wings - apply glue then slide the flat struts 11c and 11d into the openings/slots of the fuselage (segment 2). Glue to fuselage parts 11hP and 11hL as per diag. 2. According to diag. 6 glue parts 11P and 11L to join the wing and fuselage, next glue around the correctly formed fairings 11aP, 11aL, 11bP and 11bL. According to diags. 6 and 10 equip the fuselage and wings with the remaining details and parts. (Parts with major numbers 15-18).
