Mauricesellars--Now you mention it, I do remember several schools ( and not just schools ) that had this type of so-called temporary extentions to them. I guess that war damage and miss placed children was the main cause of this, plus lack of materials, time, and ignorance about the dangers of Asbestos. Only time would tell if there was any lasting damage to people's health. For a short time in the 1960's, I worked in a paper and board mill, where the process required thousands of tons of hot water fed through huge pipes above our heads. These pipes were constantly being re-insulated with asbestos, so often in fact, that they had a permenant gang of men going round the mill , removing and replacing asbestos. None of these guys had any masks or protection of any kind whatsoever. As I had to move around the mill every day ( I used to mix colourings and fixing agents) I --and everyone else, would walk through dense clouds of this dangerous stuff, not knowing the risk. Well, I'm 68, and still in reasonable nick--fingers crossed, plus anything else I can manage---NO, thats all I can manage------golightly. Ps. I can remember, the rag and bone man, hot spud man and chestnut man( though that was in the Bull Ring) a bloke selling- er, almost everything from a case, ( I used to think he was coming to stay with us) Knife grinder man, coalman, breadman and milkman with there horse drawn van,( we were ORDERED to chase after the horse for his droppings, before some other kid beat us to it, sometimes we were given a bucket) mobile groceryman, and all time favourite--the schoolboardman--?? Aaaaaaaaghhhhh-------------
