The EE is the makers mark, for Erma; earlier units were marked Erma over Erfurt in two styles.

Yours sounds like the "usual" luger sub caliber kit and box; the markings are the usual ones.
These came in to size boxes, a large about 14" long and a short one about 8" long. The small box shown below is a reproduction, the long one likely original. The boxes were often marked also.
