I agree with "washout". Whilst the engine installation is similar to the Avro 500 there is something odd about the lower wing. It would appear to pass below the fuselage. If one looks behind the gentleman's left lower arm there appears to be a gap between the fuselage and wing. similar to the B.E.4 wing installation. However I believe that whilst the B.E.4 had a 80 h.p. Gnome it had a four-bladed prop. .
