The impossible five

[dobw]

Just over two years ago I joined this forum with the express goal of educating myself so that I could avoid the pitfalls of reproductions as I try to complete my collection of WWII British infantry division patches. Usually I just lurk in the background, trying to get smarter, but occasionally I bust out with an elementary question, like this one: I'm down to the last five infantry divisions shown in Cole and Boulanger, the 8th, 12th, 23rd, 40th and 66th. Do genuine formation badges for those units actually exist?
