If the grease feels fine, it probably is ok.

The BB in my PX10 probably hadn't been touched since the early 70s. It felt horrible, but when I pulled it, the bearing and races were perfect, but the campy grease was the consistency of parmesan.

I vaguely remember those BB from my bike shop days - frankly mostly for the jokes as you might imagine. You might be able to put fresh grease in them - I can't remember.
