This set includes a complete APX-R turret, with the SA-18 37mm gun and a full interior. The gun consists of seperate pieces that allow you to model it in full recoil, or even stripped down. Of course an accurate model of the 7,5mm Reibel machine gun and magazine is also part of the set.The German modified cupola is included in the set, but not yet the original French version. The complete traverse mechanisme is also included. NOTE: This set is specifically designed for the Heller and Trumpeter Hotchkiss H39 and/or Renault R35 kits. It will not fit properly on the narrow Bronco kits. If you do not like tiny pieces, this set is not a good idea for you: it contains 78 pieces.
