Avia B-135

The Avia B-135 was a Czechoslovak cantilever monoplane fighter. It was based on the third prototype of the Avia B-35 redesigned with a new all-metal wing.

• Czechoslovakia: As the B-135 was developed after Germany occupied Czechoslovakia, the drawing depicted below is speculative of how it would've looked like if it served with the Czechoslovak Air Force.
• Germany: As it was developed mainly during 1939, it was presented officialy in the Brussels Air Saloon of 1939 under German colours. However, as Germany wasn't interested on it, they sold all of them to Bulgaria.
• Japan: Apparently, at least one airplane was sold to the Imperial Japanese Army Air Service to evaluate it. It did even got a nickname from the Americans which nicknamed it as "Alex".
