Just been watching the remake of "The Winslow Boy". It featured a character who was a Lt in the Household Cavalry (circa 1913/14). He was shown in No 1 dress wearing a flat hat. However, he was not wearing a cap badge. Now that could have been a huge error on the film-maker's part, but I suspect not. So, why no cap badge? I'm sure flyingrockdj could tell me!
