Chris R has shown us his rather lovely Anderson Shelter, on this thread: http://www.ww2talk.com/forum/other-research/22825-pillbox-bunker.html#post242949 I believe it's about Post # 34 ? Anyway, that reminded me of the brick built shelters we used to have in Portsmouth back gardens. I grew up with one ~ till my Dad and a friend spent some quality man hours knocking it down. Next door, the older lady had hers till last I knew. Then, around twenty five years or so back, I met another guy who still had one. He'd have liked rid of it. But, when I explained the drama that would involve? He decided to leave well alone. My questions is; What were those ones called, 'etc'. ? They were pretty well uniform. Obviously constructed to a given plan. It's hard for me to visualise any exact details now. Except that they were built of bricks and had a (reinforced?) concrete roof. I can only add that the 'full sized' door always seemed to face the house. Ours had a small doorway / hole in the back. Escape hole, lest the house come down on the front? I never found one with any remnant of a 'front' door showing. Don't know what was used there. Nor did they ever appear to have been sunk or buried at all. Pretty much a square, brick built, block then. I'd imagine they'd have bunks along each side. I expect enough of them still exist, in Pompey. (James ....?) What were they all about, please?
