This product includes twelve 1/144 standing Entente observers from WWI, with Lewis guns. Four observers each of three different poses are included: firing level, firing downward at 30 degrees, and firing upward at 30 degrees. You might use them in a plane like an F.E.2b or Voisin, trimming them as necessary to fit the model. This model is printable in versatile plastic and professional material (for robustness) and fine detail material (for fine detail and smooth surfaces, at the cost of being more delicate).
