I need a little education on the Leopard 2 a4, a5, a6 loader hatch. What is the correct look or configuration when the loaders hatch is buttoned up? Bot the a4 and a6 models I have are made by Italeri(Revell?) and on both the hatches appear to be meant to be positioned open. I'm unfamiliar with the linkage and how it should look when closed.
