RAF Wyton English Electric Canberra wing tip fuel tank label cut

This interesting cut is from a wing tip fuel tank of an English Electric Canberra. The tank has come from RAF Wyton and was used on multiple Canberra aircraft including the likes of WH902. 
We have chosen not to specify a single reg as these tanks were moved around. As the label that this cut suggests, the tank is an interchangeable spare. 
Approx 22x8cm and come with certificate of authenticity.
One available. Imperfections due to long term storage and operations.
The photos show the full fuel tank and it cut into two separate sections
