have a few thanks to you, eswube
I've read that initially, thought: "What the...?" But then looked at aeroflight.co.uk and everything got clear - Avro 504, Bristol Fighter, DH.9, DH.60, Martinsyde Buzzard and SE.5A and partially Lockheed Hudson (when You redo L-14).
Later there will be also Avro 621 Tutor done (it was license-produced in Poland in 1930s), but it will be posted significantly later.
