I think there were 2 types of personal Shelters, the common Anderson, which was an ouside shelterand the less common Morrison Shelter which was in effect a steel/iron table which you assembled yourself with nuts and bolts (first of the flat packs?), easier than the Anderson, that required a hole being dug before assembly. We lived in Shirley during the raids and we had the table type Shelter which we rarely used as we were not affected to much by the raids as Brum, until one night a stray bomb demolished a house in Clinton Rd which ran parallel to our Road (Cranmore Boulevard) and damaging our house, we spent the next 3 months living in an old gypsy caravan in Earlswood on a farm whilst our house was patched up and made habitable, my sisters and I thought it was great fun, I doubt Mom and Dad felt the same.
