There is in NZ a very clever man (Glyn Powell) who has made the fuselage formers from original plans for the main chassis for the Mossie. He has produced a number of full chassis as I believe and at least one full chassis has already gone to America for a rebuild for a static model (the wing sections I think were done in Canada).
Reading a further article it appears that Glyn along with help from others has not only done the chassis for this restoration but also the wings. Good on you Glyn Powell.
Have a look at this site, this is a great magazine.
