As I was walking back to get changed, I noticed noticed a pile of red and blue dummies, neatly stacked, looking very new.
I asked "what were they used for?" and "who manufactured them?". The answers were that they were used in BA training in the fire house and manufactured by a company in Wales called Ruthlee.
Seeing an opportunity here for another character, I wrote off to Ruthlee, who very kindly offered and made me a drag dummy costume suit.
Since then in my drag dummy guise, I've been used in many training exercises, being cut out of cars, used in collapsed building demonstrations, Firehouse BA training etc.
