Spit wing technical query.

This is really getting serious..As we have just about finished the major parts for our Spit fuse in 3d we have started working out the mysteries of the wing design.Have got some stuff done but getting the plan shape is becoming a challenge.We have access to a MkVIII wing to get measurements off plus using about 500 drawings.We do know the NACA profiles as well but are hitting snags as the information isn,t complete in a lot of cases.The numbers we have found on the net are NACA 2213 and 2209.4.Are these two points from the fuse centre line to the wing tip or from number 1 rib out to rib 22?
The Design of the wing is a mastery of aviation engineering and I tip my hat to the designers and manufacturers.Any tips would be a godsend.And save us from sending our draughties to the funny farm…:D
Sometimes madness is a curse,sometimes it,s a virtue…:diablo:

Maaaaaate!!!!

Stuart you are indeed a gentleman..Any info would be appreciated so send away.Hendon is a tad far for us to walk/swim to.2 Pounds Sterling equals to 85 Aussie dollars.Hmmm looks like the exchange rate has gone down..:diablo: :rolleyes:
Got to love the mother country for that.Just pm me with the detail old bean..;)
And thank you for the help…
Oh here is some screenies of the fuse loft we worked out..

All the wing ribs are measured from a vertical datum point where it intersects the horizontal datum; I can give you the mac drg numbers of those I have, and you can purchase them from hendon, at about £ 2ea (thats about $85 Aus!!); I may have a few spare copies myself if I look hard enough.

As far as I can see none of the wing measurements relate to the fuselage C/L.
