as Far as i can tell the first only says no 12... not helpful to google... the other i haven't tried to look up yet but figured id throw it out here for an easy id also if turtlefoot does come by feel free to date any of the others ive got a good ball park on them but id be curious if we agree
If the center one is brass, its old, like 1880s or maybe 1890s. The last one is from the US Cartridge Company and is early 1900s, with the "Made in USA" on it. I would guess 1920s or so.
i have before, his site was the best while i was up now when I'm looking up a stamp i usually find an answer in a thread hes replied to.
the center one is brass but as far as i can tell there is no makers name, unless that is a tiny R at the top on the rim. if it is an R and not just weathered then it could be WRA
don't know why the site turned my pics sideways but the "top" where i see the R is on the Left
The one Headstamped only No. 12 is a Remington product. I used to get dummy rounds from Brownells in the 1950's with that headstamp. They came in Remington boxes plain white label.
Don't see them much any more.
i thought older too like maybe really old, i remember reading somewhere about shells just having the gauge and no "name" but i would have thought there would be the maker somewhere and yes someone def liked to hunt down along the base of the bluffs, took me 5 hours to walk a quarter mile and that's not the first time ive detected that stretch looking for a rare stamp but this time was a disappointing amount of repeaters and shur shots.
