The image on the right is a inspection view mark which is what it sounds like you are describing. The image on the left is a black powder proof mark. As mentioned, there should also be gauge or each barrel should have a number on it designating bore diameter . For example, even though say a gun is a 12 gauge, there might be 13 or 14 stamped into the barrels which means the bores are actually 13 or 14 gauge which is how they produced "choke" back in the day.
