Photos might help, especially of the markings if they are hard to read. Most of the A.V. Roe factory built props had drawing numbers beginning with a "Y" and with yours stamped for 80 HP, if you can envision any stamping as "Y80" then it would be a match for an AVRO 504 with either the Clerget or Gnome engine.

The numbers in boxes (e.g. "A.I.D.") are inspections stamps.
