Your timing is good! I have a NIB Gee Bee 120 I just decided to sell. It is NOT Great Planes, I believe it's a clone of the Great Planes kit but can't be sure. It is the same size.
My kit is absolutely NIB with no work started. I can text you a few pictures that I took today if you are interested.
Price is $425 plus shipping from PA.
