There is a marking on the inside of the stein with what looks like a 5 leaf clover without the stem which is raised. This is located on the inside base in the middle and it is raised up not engraved into the base
There is also a flip up lid with 2 circles on it one inside the other resembling an archery target. There are no other marks other than the ones in the pictures
This piece has been in my wife's family for generations. There is a photo of her great-grandparents with the piece in the background, which places it at latest around World War I. We're trying to figure out what it is and where it came from. There are two additional similar pieces in the same condition.
