AGEE CD121 - Australia
Production of the CD121 tolls began in about 1926. Most of these insulators are made in aqua, charcoal or various shades of green & purple. These were the major Sub insulators use in the mid to late 1920's.
AGEE CD422 - Australia
Sequential experimentation with the CD420, 421 & 421.1 led to the development of the CD422 as the Sub (Subscriber) insulator of the 1930 to 1942 period.
Since mold numbers were well established by 1930, it is believed that those without mold numbers were made prior to 1930.
AGM & CCG CD423 - Australia
The CD423 was one of three styles manufactured at the Crown Crystal Glass plant in Sydney and was introduced in 1942 as a Sub Insulator.. All these insulators were embossed with the company initials CCG followed by mold numbers and dates. Some are dated directly, i.e. (19)42, 43, 49, 50, etc., but most of these units have coded dates with double dots (:) to represent the years. For example, 4::::: is for 1945, and strangely enough, 4:::::::::: indicates 1950.
By extending the rows of dots, molds could be updated without having to make new ones.
This insulator was well accepted and produced in great numbers being the most widely used of all Australian glass insulators. Embossed specimens exist in clear, very light peach, light green, medium to dark amber and pale amethyst.
CCG CD430 bottle - Australia
When ( AGM) Australian Glass Manufacturers merged with (CCG) Crown Crystal Glass in Sydney in 1942, CCG took over glass insulator production. They proudly presented their results of this merger with the introduction of the CD430, dubbed the new Trunk insulator.
Unlike its forerunner the ill-fated CD432, the CD430 was a sturdier insulator and most of all it was a success.
C.C.G. CD430's exist in a wide range of beautiful colours including clear, straw, smoke, light green, peach, chartreuse, medium to dark amber and several shades of amethyst.
AGEE CD490 "Bell" - Australia

The CD490 Type I AGEE bells were introduced in 1926 along with the CD121's. Glass colours are medium to royal purple, pure gray and two tone light amethyst with green.
We refer to these earliest AGEE bells as Type I because of there narrow, straight sided domes, rounded wire grove rims and nearly flush inner skirts. These were the major Trunk insulator in use during the mid to late 1920's. The Type I began having problem from the start due to neck fractures and shallow wire grooves. The Type II was introduced somewhere between 1928 - 1930, still fragile, but the inner skirt was raised a bit and the new wire grove rim was sharp and angular. Mold number are embossed on all these Type II bells.
Further improvement followed with the introduction of the Type III CD490 in 1930 as the glass Trunk insulator of the 1930 to 1942 period. Maintaining the raised inner skirt of the Type II bells, this new style proved to be more structurally sound. All Type III bells have mold numbers and dates. These insulators saw limited production because of stiff competition from local pottery. In the mid to late 1930's a company known as Robert Fowler Ltd, of Sydney, began turning out thousands of large porcelain bells called U-1502 which was the demise of the CD490.
The U-1502's were a failure by their very design and were later replaced, after much testing against other styles, with the U-1154. This became the new porcelain Department (P.O.) Standard known as "Insulator, Trunk, L.S." (long skirt) I have examples of this style dated as late as 1981.
Style II - mold 5
Style I
Note the 3 different skirt heights on the above CD490's
These two pictures (above & left) are of the CD490 AGEE with the 4 drip points. These are reasonably rare to find.
Just a matter of interest, this baby's bottle was also manufactured by AGEE.
AGEE CD154 - Australia
Sometime between 1929 & 1930, Australian Glass Manufacturers received a special order for CD154's from the South Australian Government. As far as we know, most of these were produced during that time period and were used only in that state. These insulators have mold numbers and round drip points. Glass colours are sage green, grey or medium to dark purple. With its American threaded pin hole, the AGEE 154 is a copy of the familiar Hemingray 42, which was being used in South Australia at that time While both units could be, and probably were used side by side on the same line, the AGEE 154 was designed to replace its American twin.
I am after more colours in the styles shown on this page, can you help !!! Also wanted CD154's, CD420's, CD421's, CD421.1's, CD422's, CD432's, & CD590
