I hope no-one minds me posting this here but I saw the following in todays paper and I think it's a worthy cause:

'The surviving battle of Britain veterans have produced a fantastic and moving book about their epic few months but cannot find many buyers because they can't afford advertising.'

The book costs just £7 including p&p and can be bought from:

The Battle of Britain Historical Society,
Gunthorpe
NR24 2NS
