EIN 040 embossing minus the most of the T pa PAT and the P of SEPT due to two opened bubbles under base. Don't think you will be looking at the embossing as much as you will be the unusual cluster of bubbles about centered on one side of this insulator. There is also a much larger opened bubble that is centered on the right side mold line at base of dome. That is a little longer then 1/2" in length and about 1/4" wide. the top of the dome has a fizzy milk swirl on one side and it looks like the upper part of the unthreaded pinhole has some milk. More smaller bubbles scattered around other then the main featured cluster. Even though this insulator doesn't have a single large bubble the cluster will without any doubt draw your attention. Other then what I've already discribed this insulator is mint condition.
