Tube ID anyone?

Can anyone ID these tubes?

Notice, the copper wiring, and poles, the shape of the grid, and the indention on the o-ring support.

I want to know what they are
I can't find any 6dj8 tubes that are neutral for under $25

Has anyone seen tubes like these before? Thanks

It definitely appears to be a twin-section tube with an internal divider. Does the divider come out to pin 9? It kinda looks like a space charge tube, but not sure.

Yes, it does.

I found out what it was, NOS 6922 made in slovakia during slovakia's communist era.

also there is a 6dj8 like this made in china from 1990s +
