Used them in the RAF many years ago and managed to get one at auction last weekend. There were 6 for sale and the one I selected got filched and I was left with one but alas it has some problems. One step missing and two others damaged along with missing wheels! It is usable as I have just finished cutting my hedge on it but would like to repair it to as it should be. I have tried a search on the web for military breakers but no luck. Anybody know of the people who deal in that sort of thing? They are "A" ladder 5 ft high by the way.
