Hi Jeff
The serial number on your fabric 'N591' or 'N591x' can tell you something about the aircraft.
"Royal Navy Aircraft Serials and Units" says that 'N591' was never used and the series 'N591x' was used on Sopwith Triplanes N5910, N5911 & N5912, the rest of the series was cancelled.
The 'Sopwith Triplane' Datafile has pics of N5911 & N5912. The serials are applied to white rectangles on the rear fuselage and don't appear to have any numbers on the tail stripes as on your fabric.
Also N5912 still exists at the RAF Museum at Hendon:
Sopwith Triplane
So probably not a British aircraft, maybe a French Nieuport??
Or fake
