The following picture shows a very close-up picture of the internal rim continuous drip point ring. The internal drip points show up best on the bottom right side of the picture of the rim. Note, neither the skirt embossed and center embossed CD 112 S.B.T. & T. Co. had the internal dome glass button. Several ICON members sent e-mail indicating that some of their Southern Bell kegs had the typical glass button normally present in the "pennycuick" style insulators. I was asked to check mine for the a glass button. Also, three people think the CD 112 No Embossing insulator I have is a "pennycuick" even though it too did not have the glass button on the inside of the dome.
