Here is my lower stamped "3", (which has a raised dot near the hinge), and my higher raised "3" to compare.

Nice examples Ralph. Random dot on your lower 3 as well, and certainly looks like a drop of solder. I guess mystery solved here, funny how we don't really notice these drops on the high 3 variants.
