Peters Victor box and unfired shells

Hi all,

My grandfather passed away a few years ago and this box has been in his gun cabinet for as long as I can remember. I’m wondering if anyone could shed some light on what year(s) are possible for these or any other info. I really know nothing other than they do not mention Remington and have the Kings Mills address, which from my readings means they are pre 1944.

Thanks for any info.
