Hello to all, I am known as lofty as the fact that 3 generations of Grenadier's can attest. I am 74 living in Devon, I have had a life long interest in the Defence of London I.E. Air raid shelters, Emergency Water Supplies and Sirens. My father started the war as a regular NCO Grenadier he spent some time at No 1 London cage and also Kempton park racecourse guarding German prisoners. I shall now go and post a question. Lofty
