RAF in Camera 1970s by Keith Wilson and published by Pen & Sword follows on from his 1950s and 1960s volumes. Got mine today and it follows the same format as the earlier volumes using official photographs, is mainly in colour and looks like an great reference source for the RAF during that decade with green and grey Phantoms, Harriers and Jaguars everywhere just for starters.
RRP is £40 although I ordered mine through a third party seller on Amazon for £32 last week and on checking again this morning the same source is now offering it for £28 with free shipping.
Hope that the 1980s follows in due course.
