1950s
I lived in Preesall from about 4 years old in early 1950s until about 13 years old and my dad showed me the target many times from road. You had only to cross across cockerham sands when tide out. Quite a few vehicles got caught by inrushing tide. He told me it had been used as a practice target in 2nd world war. It was hard to get to due to the ditches between the hillocks.He did say you could find bullet leads around site. I went past years later and it had gone.
