These are simple but clean sets of precisely cast resin replacement parts that quickly and easily improve already good 1/72 scale early P-40 kits. Each set consists of one gray resin block with easily removed molded parts. The hollowed-out exhausts, scale thin damper cooler flaps, machine gun barrels with oblong cooling vents, and detailed undercarriage covers (landing gear doors) are intended for Airfix’s new-tool 1/72 Curtiss Hawk 81-A-2 (P-40B/C) kit, but can fit other kits as well. QB 72 374 has two rows of six round exhaust pipes attached to the resin block by a narrow feed that can be easily sawed free, as can the Damper Cooler (the cowl flaps underneath the rear end of the engine).
