RAF museum UK, would most likely have it.
I have been building a 1:1 and they were helpful. 3d scanning works if you have a plane in a museum you can get acces to
I'm also building a mk v and noodled around and got a full set which took awhile, found them in different places. Get the parts catalog so you can map drawing #s to parts, you can get that from the raf museum. Also recommend getting a copy of the book; spitfire engineered by Paul Monforton...
I'm a bit late considering the dates on these posts, I am working on a scratch E and wanted to see if you were interested in selling a copy (help cut your costs) ? thanks
