Given that G-AKDN was one of the two initial pre-production airframes, where she began trials testing in April 1948 and the fact that she was 'owned' by a member of the Derry Family ... I suspect one will require a very large sum of money. I'd also guess that being a pre-production airframe, despite any later mods during her lifetime, there may still be some servicing and maintenance idiosyncrasies to contend with ... Which more than likely will add to her running costs.
But let's hope someone will have the necessary resources to keep G-AKDN airworthy

Dora-9's comments if I may ...
The deeper chord rudder was a specific requirement issued by the RAF. Primarily to give greater control authority in keeping the nose up during slow rolls together with improved control during side slipping and X-Wind take-off and landing. This mod was
not introduced to improve spin recovery ... but it did give 'improved' spin entry.
