M3 Stuart Turret Roof internal details needed

[carl brown]

I am currently restoring the turret of my M3 Stuart and am in need of some detail pics of the inside of the roof of the turret. The turret is a later 2 hatch model on an Ex Australian M3.
I need to fabricate the mountings and hinge for the signal hole assly and the angular roof stiffener and rectangular mounting plate that is welded next to it.

I have the blanking plug that goes in the signal hole.

Can any one help with pictures or dimensions please?
