OCIndeed, my mistake. Trying to use a somewhat damaged onboard data recovery system. Refering back to references, these boxes indeed were seen during the 1950s and early 60s, not prewar.
The 1st 2 on the left are made at Frankfort Arsenal in March of 1886 and have copper cases. These have the 500gr lead bullets and are intended for rifles, not carbines.
The next 2 are also made at Frankfort but in 1892 and 1896 respectfully. (Originally I called these Bloomfield guilding cases but in fact that is not correct. These are tinned brass which Frankfort began using in 1888.)
The last cartridge is a much later commercial offering, with a 405gr bullet, simply for comparison.
Though I am not a big fan of this caliber these are some of the first cartridges I ever bought simply as collectables, some 20yrs ago I guess.
