Hi, Sorry to post copper here, but I'm getting stumped finding out what this "cup" or tankard really is anywhere on the internet. It could be a liquid measuring cup, or maybe a tankard? I'm American, and don't know what the marks around the rim are, but think they are "verification". Seems strange there are 15 or 20 of them, all over the rim, one after another. Can anyone help?
Thanks
