Close up of the "common purple" AM TEL. These were used by the zillions on lines out of Denver. I have heard many people call this the Denver Mold. See photo No.1 and No.2 for comparisons. Does not closely resemble R.Good, WFGCo, or WGMCo tools like the unit in photo No.2. Note the flat-topped "&" found ONLY on this style. These are unknown in any color but purples. Most a deep lilac shade like you see here.
