Most, if not all, planes used in this film were either replicas or modifications using existing planes.
It is a Standard J-1.
A Curtiss JN-4 'Jenny'.
For the crash scenes a modified de Havilland DH 82A Tiger Moth replaced the Curtiss.
It is a Bücker Bü 133 Jungmeister with an engine modification, probably a Lycoming. The original radial engine would have looked better for a film playing in the 1920s.
Another Curtiss JN-4 'Jenny'.
Here the Standard and the Curtiss fly in formation. Nice to see how similar they are.
Another Standard J-1.
It is a modified de Havilland Canada DHC-1 Chipmunk, first flown in 1946.
You are right, a replica of a Sopwith F.1 Camel. Seven originals have survived until today, none airworthy.
Indeed a replica of the Fokker Dr. I Dreidecker. No original has survived.
