I think these two videos are of Wrens Warren Camp School in Coleman’s Hatch, East Sussex and have recently been released on youtube by British Pathe news. The similarities to Wyre Farm Camp school will be obvious.
The first is an edited version with voice over and the 2nd one is is silent with a lot of unedited footage. Read more about Wrens Warren Camp School here on this very site http://wyrefarmed.blogspot.co.uk/2013/08/wrens-warren-camp-school-national-camps.html
