RE: What is this plane?
Well, then Kadet would be my best guess. I've never built the Mark II, but have seen it fly. The current model has an ABS cowl, could have been glass on original.
It's great to breathe life back into an old ship. Very few would go to the trouble, it is a challenge which will reward you with satisfaction, and it is nice that you have others in mind who will benefit from it. Keep us posted with pics of progress.
