The "Division of Olin Industries" stamp was used from 1944 to 1954. The 42 punched into the box is a box makers mark iirc.
The Western box date code is the 22RL 52 (98 is not identified, may be a shift code).......... 22 is the packer, R is 1960, L is October, 52 is the day (reversed) so the 25'th day.
Don't have the Remington codes I'm afraid, have seen a few posts with partial info on the International Cartridge Collectors forum but no complete listing. Best I can do with Remington stuff is go by the known changes in labels, box designs and addresses.
