Dear friends

I have come across the following speakers used in Philips radios.

1. 49.238.16
2. 49.238.17
3. 49.240.17

What is the basic type no of these speakers. I have got only the above code nos. Are their any other details available? The the 1st and 2nd speaker were used in the set Mullard MAS231 and the 3rd in Philips BCA405B.

Thanks

Regards
