While this model is still available, I recommend the updated observer models with poses at multiple angles, linked below.
This product is an array of thirty 1/144 observers for WWI aeroplanes. This set has 20 observers with single Lewis and 10 with double-Lewis. Guns are modeled as close as possible to correct proportions given the limitations of FUD material. A box structure protects the model during shipping. It is intended that you can snip off an observer, trim, and glue into existing crewless plane models. This also works well for replacing crew on WSF models, which -- while cheap -- suffer from lack of detail on the observers. Frosted Ultra Detail material assures the finest detail possible for the observer and the guns.
