WANTED: Traditional Regentex Canvas in 40' or 50' wide

Description

I'm looking for some extra canvas to extend my 40' & 50' traditional marquees.
I bought all my marquees from Dover Marquees Co Ltd so if anyone else bought any of their kit that they no longer need please get in touch.
I'm interested in the roof sheets as well as the hip ends and also any walls.
They have to be in good condition as we mainly use these marquees for weddings.
