armour details of early war British tanks

I've spent a while using Google trying to find details of the armour of some early war British tanks, in particular details for sloping armour. I haven't found anything about angle of slope.

Here are the gaps I have:

Mark VIB light:
depth and slope of: superstructure front, superstructure side, superstructure rear
depth and slope of: turret front, turret side, turret rear

A10 cruiser:
depth and slope of: superstructure rear
slope of: superstructure front, superstructure side
depth and slope of: turret side, turret rear
slope of: turret front

A13 cruiser:
depth and slope of: superstructure rear
slope of: superstructure front, superstructure side
depth and slope of: turret side, turret rear
slope of: turret front

A15 cruiser:
slope of: superstructure front, superstructure side, superstructure rear
slope of: turret front, turret side, turret rear

Thanks very much,

Neil
