| Descripción |
Driver for Class B.
Metallised bulb.
There is no other documentation known but in "The Broadcaster" April 1935 Supplement "Service Engineer": Ever Ready model 5001 where the PM2D1 is noted more than once.
It can be suspected that by misunderstanding in fact the PM2DL is meant, which apparently is quite similar to what can be seen in the a.m. paper.
