The date is a rough (somewhat) educated guess.

TF-BU to the right and TF-BZ in the middle. They probably belonged to the Fliegerfürherschule A/B 116, which seems to have been based at Neudorf-Oppeln until 1941. the Arado Ar-65 was a German fighter and first flew in 1931. The first models were delivered in 1933. The aircraft was demoted to trainer in 1935 and production was halted in 1936. In total, 85 aircraft were built. The other aircraft that are visible in this photo are North American NAA-64's, captured from the French Air Force. Many thanks to Tom Willis and the AirHistory editor team for identification and information! Photo from W. Muntinga

Developed in the early 1930's as an advanced (fighter) trainer aircraft. The first prototypes flew between November 1993 - February1934, with production beginning in 1935. Around 1000 aircraft were built and mostly used by Germany, Austria and Hungary (although other countries took deliveries as well). It was said to be highly popular amongst pilots due to its aerobatic capabilities and handling. The listed c/n and s/n is unconfirmed. Photo from W. Muntinga

Entered the Dutch register in October 1937 for NV Autogiro Import at Hillegersberg/Waalhaven. Destroyed there on May 10, 1940. The location could possibly be Oostwold (before it became an airfield), as the aircraft made an emergency landing there on 25 May 1938. Photo from: W. Muntinga
