The microphones came from different sources, but both had been modified in the same way. The mods were performed long enough ago that the foam had started to disintegrate.
In both cases the ribbon element has been replaced by a dynamic element. and the mic stuffed with pink foam. Both mics are painted black with a silver top, and in both cases the stand adapter is fixed to the microphone rather than being removable.

There are clearly a few of these floating around. The stand modification looks well done, and I suppose it is just about possible that this was done at the factory, perhaps as a budget alternative to the ribbon mics, although I have not seen any documents to support that.
So, look out when buying old microphones - what you see is not always what you get.
