Yes, that is the year that they were made. When you purchase your brass, did you have a choice of GRADE 1 or a GRADE 3? I so, grade 1 will already have the primer and crimp removed.
If you are having no problem putting a primer back into the pocket, they probably have already been done. Since the brass is bulk military, I would take a Lyman crimp reamer to each case after de-priming just to make sure. If there is no crimp, you will know right away. One other thing, you may have to use a small base die if you have a custom chambered rifle or a semi-auto....JOHN
