Golden Flute - Dugan Diamond
Probably made around 1930. It was named by Angela Hallem. This vase has 12 flutes and base sizes vary between 2 1/4 and 2 1/2 inches.

Only known in marigold.

Optic Vase - Diamond
Known in marigold, amethyst, and light blue with 14 subtle interior panels. Writing in the December 2004, Carnival Pump (International Carnival Glass Association), Larry Keig says:

"The Optic pattern seems to have been confined only to vases of a moderate size. They range in height from about 7.5 inches tall to a bit over 9 inches, depending on how much they were swung during production. A simple pattern made up of a paneled interior and a star base, they are plain on the outside. The 23-point star is pressed into the exterior of the 2.5-inch base. The configuration of their tops is characteristically Dugan/Diamond, the hexagonal flat-paneled treatment that is also seen on most Circle Scroll, Lattice and Points, and Nautilus and on many Standard vases."

Thin Rib - Diamond
These Thin Rib vases seem to have been produced by Diamond in great quantities. They have six ribs, a starred base with a diameter just under three inches, and are found mostly in marigold. The heights on these small thin vases usually range between about eight and ten inches tall. While marigold examples are common, other colors are scarce.
Ten Thirteen R Vases - Dugan
A scarce vase. Note the flames. These are the flames found on Target vases, and while this vase has the six ribs of the Target, it has no hobs. Spiralex and Wide Rib vases have eight ribs and very different flames. This vase was shown in old ads, designated simply as "1013-R."

This heavy, substantial vase has a base diameter of 3.75 inches with a 36-point star. Heights seem to range from around 9 to around 13 inches. Although produced in several opalescent colors (named 1013), the few carnival examples are marigold and peach opal.
