I enjoyed reading the article you are refering to
Ball park I would guess at about £4000. Spoke to a chap who recovers wings and he said that he could do them for about £1800 labour plus about £400- £500 materials.
For this they would recover a stripped set of wings and finish in silver dope. The guys who do the work were retired so the work is done on a semi commercial basis.
Have you had any look finding an AOP 9?
Just put some pictures of my
Auster on the net if you are interested.
