looking for info or drawings on the LAV top turret, specifically the hatches. I need the inside face details of the hatches and the CORRECT inside diameter of the hatch openings. (I mean really, what was Italeri getting at? they look 1/48 when the hatch is opened and you can see that little hole, especially with a figure in it.)

I know hunnicuts book is out, but it is a lot of $$$ to drop for a couple of drawings. Any help appreciated.
