Thanks vidbib.

Looking through the patents, it appears this is a radial version of the scheme embodied in figure 6 of this patent US2071516A:

Also similar to figures 5-8 in US2143262, but without the split cathodes:

Any speculation is welcome.

I'm hoping to find out from Eric Dollard at some point if he ever played with this exact tube, since it was in Philo's son's collection, and he may have come in contact with it.

USPS estimates delivery Monday!
