149 Celluloid Dial PlatesThese were issued on #4 and early #5 dials. They featured a painted dial face that was covered with a celluloid coating. The celluloid coating did not prove to be durable and Western Electric eventually reverted to enamel
149 A: Common numeric "Rural" dial plate used on exchanges that did not use letters.

149 B: Common alphanumeric "Metropolitan" dial plate used on exchanges that used a combination of numbers and letters.

This one has II 34 and 149-B stamped on the back. It also differs from later versions by the odd tab on the back:


Later versions saw the date and model # moved to the front. This format was used for all dial plates that followed, with the exception of some 6a and 164A plates (see below)
149D: Similar to 149A but has "LONG DISTANCE" around the 0 in place of "OPERATOR"
149E: JMRW "Party Line" dial plate

149 H: Blank white dial plate used on pay phones in conjunction with a "Daisy Wheel". This one is stamped "149H" on the back.
Solid Celluloid Dial PlateIssued in very limited quantities for a short period, these dials did not stand up well to regular usage and were withdrawn
