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.
This item is basically an upscaled version of my 1/300 scale model. I have added a pilot figure and thinned the struts.
