Thanks, Tophe!
The model consists of the leftover fuselage from an MPM Lockheed Vega (it came with 2!), the wings and tail surfaces from an Eduard Overtrees set for the Avia B.534, engine/cowling/prop from an Airfix Kingfisher, and skis from the Airfix J.8 Gladiator, all in 1/72 scale. Markings were made up from red, white and black decal film.
