Yes, I've seen the High Planes Avon Sabre. The problem I have with it though is that a) it works out pretty expensive (thick end of £20 for the conversion and the donor) and b) the real life Avon Sabre doesn't look much different to the normal Sabre unless you put them side-by-side.
Now on the other hand, I've already got an Emhar FJ-4 which was cheap becuase the box is tatty, and a couple of other projects that will leave me with spare F-86D wings anyway.
