This study focuses on a WWII Supermarine Spitfire aircraft section wing conservation, salvaged from the seabed in 1988 and stored in a private garden. The object was in poor condition so decisions on the conservation, preservation or removal of parts of the original elements were needed. Firstly, the wing fragment was studied to determine its heritage interest and to assess its historical, industrial, technical and scientific values. This object will become a memorial to the pilot who died during the mission, in his hometown. The conservation project aims to find the best solution to both conservation priorities and exhibition needs. Based on cleaning tests on corroded, painted aluminium alloys carried out within the PROCRAFT Project, a treatment was determined. This case serves as an example of how the results of a European project can be implemented in a conservation-restoration process and how industrial conservation theory can be applied to archaeological artefacts.
