The Messerschmitt Bf 109 was the backbone of the German Luftwaffe. Versatile, tough and well armoured, this nimble fighter was one of the most advanced aircraft of its era. Yet, even the perfect plane can be improved upon. The G variant was designed with a reinforced wing structure, bullet-proof windscreen and additional light-alloy armour. This gave the plane even greater versatility in combat, so much so it became the favourite of Erich Hartmann, the world’s top scoring fighter ace. Lavishly illustrated and filled with A4 drawings, this booklet is the perfect choice for any aspiring aviation modeller.
