Dimensions needed for vision slots and more

[Sgt Shultz II]

I need the dimensions for the vision slots mainly verticle and horizontal, jusat the rectangular shape.

Would also like recommendations for a manual for references to help build and detail a model of an updated Mk I Carrier.

Is there a listing of serial numbers for Carriers made in Canada and Britain?? Also are the serial numbers the same as the markings on the side???
