I need to identify some philips speakers, in order to source a replacement for one of them. They are identical 10 inch units from a high end radiogram from the early 1950's, the FX804. The markings on each speaker are as follows:

4923952
52
39
3

Hopefully some of our friends in Holland will be able to make sense of these for me. With thanks, Jonathan
