Lockheed Hudson - The First Cut
One of the first steps in the conversion to re-fit the Boulton Paul upper turret was to remove any excess material from the fuselage. This meant cutting a hole in the upper rear fuselage, and removing the skin and additional structure which had been replaced post war. 
After taking a template form the structure of A16-128, the skin was cut.
After the initial cuts and removal of skin, it was decided to completely remove the inaccurate upper rear skins from the fuselage, to gain access for repairs, and to fit accurate replacements.
Work continues on the fabrication and conservation of internal structure and components.
