But something happened, and I will be happy if someone who reads this knows a way to discover more.

"Received a Queen's Award for Bravery for protecting a group of spectators (during filming of a first season episode of Robin Hood) by grabbing the bridle of a horse, which had bolted, and was drawing a cart with fixed axles that could not be steered. The cart ran over Duncan, fracturing his kneecap and putting him out of action for the next eleven episodes." http://www.imdb.com/name/nm0241902/bio?ref_=nm_dyk_trv_sm#trivia (imdb trivia)
According to this, in the 1950's it was called the Queen's Commendation for Brave Conduct, and the name was later changed to "Commendation for Bravery" in 1994.
I would love to know more about the particulars of this award, as Elizabeth hadn't been queen for very long, and the brave act was done in costume as Little John, with a medieval-style cart, on a film set. It must have been mentioned somehow in the presentation, on in the certificate.
