P.Z.L. P.46 Sum from the left
Here we see one of the two completed prototypes of the P.Z.L. P.46 Sum, a light bomber and reconnaissance aircraft that was almost ready to enter production in 1939, but was delayed when fighters were given higher priority. This may be the second prototype, as it appears to lack the strips of metal added to the first prototype to mask the gaps between the main sheets of metal on the fuselage.
