I have the brass case version that you show coming from the box shown below at right with the factory-blackout marks over the words “nickel plated case”. That box has an F code lot number for 1952, and they are the same cartridges except that mine have the serrated crimp up high, and the smooth crimp down low.
The nickel-plated version you show, I have in the other box shown below at left. This box with the “nickel plated case” and red “lubricating alloy” print has an N code lot number for 1938.
I believe the box with the blackout print is quite rare, and beyond just having the two versions shown below, I presume there is a version which shows the “nickel plated case” text not blacked out, and I also have a fourth box which shows neither the “lubricating alloy” print or the “nickel plated case” text at all - however this box came with nickel plated case loads anyway. Then of course you get into a couple variations of the later all-yellow box, and then the most recent all-white boxes. The very first box in the mid 1930’s was the Super-Speed box which had two versions. There is a lot of variation on these, with things like single crimp, double crimp, case metal, bullet ogive (2 types), headstamp, and the type of crimp and I must have 10 or so .38spl variations from the 1930’s to the 1970’s. I have 5 box variations on the .357mag metal piercing type with as many cartridge variations.
The Western box codes are described here that I referenced from:
