A take-off (no pun intended) from the similar auto and truck thread. Let's see what is flying around your layout.
I'll start with one item that is special to me. Almost 60 years ago my Uncle, who worked for KLM, gave me a cool wind up plane. I loved it but it disappeared over 50 years ago. Recently I was telling my cousin about it and guess what she found and gave to me? It turns out that her father also gave one to her.
For reference, the wingspan is about 12 inches. It will shortly be hung over Warrenville with some monofilament fishline.
I am pleased to share the two pics below:
