My first post, so I take the opportunity for a very brief introduction. I grew up on World War I stories as a kid, told by my father (who was himself a WWII bomber crew FE). I am glad to see this site.
I found the site while looking for a particular squadron insignia which I remember from a book I had yonks ago. I think it was on DH4's(?), correct me if I am wrong, as my memory probably fails me. It was of a boy doing a double nose thumbing (a rough example posted as an attachment here, that I did on inkscape).
What squadron? Does anyone have a better image of it? I have not been able to find it.
