Sadly I only have dates for those Radium lamps made by or under licence from Osram, for which the coding is the same.

Yep I too have the 4 digit codes as the same with OSRAM/Sylvania Codes example b618 and so on,

I wonder if they are the same as the older OSRAM/Wotan Codes as from 1974 to 1994, example x9 = x = 1990 and the 9 = September which makes sense.
