Wanted stringer section to salvage and Piston Provost parts.

Hi all

We need some pieces of stringer section for a static Piston Provost project. So does anyone know of any scrap Piston provost / jet provost / Chipmunk even a light aircraft etc fuselage structure rotting away anyware that we could salvage some stringer sections from? We will consider literaly anything with standard stringer section in it of any lengths.

Also any Piston Provost cockpit area part down to the smallest item considered, literaly anything!

Thanks in advance.
