Hi all,

I would like to ask for some help with my research of above mention turret.

I found some information on the internet which was taken from book:
Wallace, C. R.: British Aircraft Armament Vol.1: RAF Gun Turčete. Patrick Stephens Ltd., Sparkford 1993.

I would like to ask if any member has this book available to make a check of some details for me?

I am also interested if anyone could provide me with advice where to find closeup photo of FN7? I am interested mainly in the rear escape doors, i.e. their size and position.
