HI. I need help marking shell lots and fuzes. In the first photo they are clear. CY 613 (Chorley) for shells and RS 853 (Rotherwas) for fuzes

The following presents the shell lot in the circle (365) and the fuze lot at the bottom CY 146

Do the following two boxes have the fuze lots in the circle and the shell lots on the left? Or is there a regulation for these markings in the circle?

Thanks for your help
