Hi Glenn.
I think someone has made a start on this as the two are no longer linked but some work may remain in respect of the model's and cn's.
The situation of model designations/names being changed when military airframes are transferred to a civil register is all too common.
I have been editing Piper profiles in the database and Military L-4 Grasshoppers are shown as J3C-65 Cub's and vice versa, with linkage involved. As there are so many which were built as L-4's, I have resorted to calling them L-4 Grasshopper (J3C-65) in the hope that this will be acceptable when seen against the linked civil registration. To de-link them would be too time consuming.
In your paricular case, which involves a single airframe, they should be de-linked and cross reference notes added to each profile.
Malcolm.
