Hi Al, I have the same valve data book (Iliffe) it seems none of the valve pinout diagrams show pin numbers, my repair techs. brain would normally say number and read clockwise but as you say in the case of the EM1 etc it is opposite to the normal convention, maybe that's why the data book does not give actual pin numbers, to avoid possible confusion etc.
The purely pictorial representation of the pinout showing the electrode connections is correct. Must admit it's a new one on me also.
