The dials are huge factor in determining the value of WE phone. The #2 dials, with the fingerstop screwed into the side of the dial are most desirable. With that great clickety clack sound. These sat on the phone, not inside and only fit on a B1 102, a candlestick and a WE 553 Wall phone. Next in line is the #4 dial, great clickety clack sound, most are upgraded #2 dials, but not all. A brass 5H made in January and February of 1949 is also a nice dial. The #5s and the #6 end the run. As Darrin said, the zero placement is the key with distinguishing dials. Zero at 6PM its an AE type dial, 4PM its a Western. A good #2 with a notchless plate will set you back $100 +. Educate yourself on the dials, almost as much phone as the phones themselves....Doug
