The PWS-10 was the first fighter plane designed and produced in Poland. Its first flight was in 1930
After the outbreak of the Spanish Civil War, the Nationalist forces bought 20 planes that were smuggled in via Portugal. After a few month of active service more modern German and Italian fighters became available and the PWS-10 was relegated to training duties.
In Poland in 1939, it also served only in training units, but it did see some action when Germany invaded. Wikipedia
has more information about the original MIcro Armour Mayhem
has pictures of the model painted in Polish colours (scroll down from the link).
This item consists of 4 aircraft in 1/300 scale on a sprue. I have simplified the elaborate strutwork of the original to accomodate the material limits. No pilots are included. Shapeways' Reduced Aircraft Factory offer pilot figures
that can be added.
