"The only alteration was the fixing of an escape hatch to the cupola-roof of most vehicles."
Acording to the article on the main site. However, I have been unable to find any picture showing this hatch. Would anyone have any idea where I might find such a picture, or a drawing or something?
I wish to build my Mk IV "Female" in this manner, and knowing how the hatch looks like is better than guessing.
Not only a hatch, a compass (same as used on A7V turret top) was added as well (after July 15th, 1918). The upcoming Tankograd 'Beutepanzer' book will have some pictures showing hatches and compasses.
