I've put this model together over the last 2-3 months, in between projects. I finally finished the base.
The plane is a Trumpeter 1/350 Martin T4M torpedo bomber, with PE struts and wheels. I whiffed it by adding a cowl ring.
The base is gray Depron painted white, roughed up a bit with some ruts. I found an airfield image online that I printed onto decal film and applied to the Depron.
The building is a 1/144 scale paper model shack that I scaled down to 1/350. I added some grass bits as well. The figure in the overalls is a Northstar US Navy 3D printed figure.
Trumpeter doesn't include a torpedo and the engine is just a slab - I painted the cylinders on the clear plastic and hid the details with the brass cowl ring:
It was a fun little project, the most annoying part was the clear plastic Trumpeter insists on using for these small planes.
