Western Electric "Z Operator" 164A dial plates
« on: November 27, 2013, 09:50:37 PM »
I got a couple of these in a lot of dial plates.  I always thought the "Z" was discontinued once the 164A plate came along:

I've seen that black dot just above the fingerstop on a few color 302s, but I don't know its significance.

To the best of my knowledge, the black dot means the dial is #6 type. The 164 plate only fits 6 dials, so black dot=6 dial.

I believe that the black dot indicates that the plate is meant for a dial with a clear fingerwheel like those found on colored sets.  Also, 164A plates are backwards compatible with earlier Western Electric dials.  The earlier 132, 149 and 150 type dial plates will not fit a #6, however.

Actually, I think a 132 dial plate may fit a #6

Here is another dial plate I dug out of the parts bin.  It looks as if WE made both styles (150 and 164) at the same time during the Korean War or thereabouts.  During this period they did away with the Z so that early 164A have it and late 150B do not.

The black dot indicates that the *dial* it is found on is a 6-type---6A (black rim) or 6D (white rim for color sets). The early 6-type dials did not have "6" stamped in the finger stop. Later, the dot on the number plate was eliminated once the finger stops were marked instead. Also, the early plates were not 164A since they fit *only* 6-type and the 164A plates are universal--for 2-, 4-, 5- or 6-types.

132 plates are not notched so they won't fit anything but a #2. There are some similar looking notched plates found on 4H dials from 1930-1934, but these are not marked "132."

That makes a lot more sense.  I have a couple 6Ds that do not have the dot, and I really did not feel like removing the fingerwheels to swap in my new "correct" dial plates!

Now I see it-it does not have the holes for the retaining ring.

Is there a part # for those early notched plates?  I always thought there were 132 "notched" and "notchless".  The notched does fit a #6 by the way.

I think I feel a reference thread coming on...
