CAS[w] - Boulton Paul Defiant

A Boulton Paul Defiant [fin number - N1585] from 264 squadron at RAF Duxford. It was shot down in May1940. {colourised image}
[note turret - looks remarkably like a Parnall Aircraft product. If it is one of them, then my late father was partly responsible for making the turret work. He found a way of making the nuts & bolts that held ball bearing races in position actually fit properly].
