After numerous trips south of the border by my partner Richard Cook of Benson, Arizona, and me, we have not found too many different glass insulators. We have, however, found about ten different types in variations of colors from aqua, blue, green, amber, off clear and clear. The colors can vary in many different greens and blues, especially in the CD 155 RYT and the CD 454 or 154.5 Derflingher TN-1 types.

We have also noticed that the Derflinghers are more often no names than with embossing. Also the Derflingher type will be in two different sizes. Some have the large dome, especially the ones embossed DERFLINGHER TN-1, but most of the no names have a somewhat smaller dome.

We also noticed in Mexico, as in this country, as the telephone lines are being worked on, the glass insulators are discarded, and the new white plastic type, base embossed HECHO EN MEXICO AIROVA are being put into use. These insulators look like milk glass. A picture of this is on page 10 of the December 1973 issue.

The latest additions to my collection, which now totals fifty-eight different in all, are the items pictured below. Refer back to the December 1973 issue and the April and August 1974 issues.

(l. to r.) CD 155 RYT Upside Down Emerald green, CD 106 PSSA #9 Flat Top Light Green, CD 454 or 154.5 No Name Derflingher Light Yellow Green	CD 162 or 162.7 FFCC N DEM Type No Name Amber

The PSSA-9 Flat Top is a light green color. The No Name Derflingher is a beautiful light yellow green, almost straw color.

The rarest insulator that Richard Cook and I have been able to find so far is the CD 162 or 162.7 No Name amber. This one is the FFCC N DEM type. It is a beautiful dark amber

The RYT is a very beautiful emerald green. It is the Upside Down RYT type.
