Drawing by Tapani Tuomanen

The most interesting part of this plane is its unusually colored engine cowling.

This was something interpreted as a piece of olive green cowling from another plane.

If so, the piece should show a light grey lower sector, clearly absent on the image.

So, we preferan interpretation as a fast identification marking, possibly red.

Other characterizations to this plane are given by the number 29 on its rudder, apparently black, and by the presumably red cap with thin black outline on its tail.
