The B-17 is a hand built Guillows kit – beautiful! 42 inch wingspan. The B 52 is a scale. monogram kit – beautiful. 32 inch wingspan. They both have been hanging in my office for years – the World War II big bomber era, and the B-52, which is still flying. I’d love for someone hang them up in their office. They’re quite a conversation piece. I can’t take them with me. And they are both free – need a new home!
