I am now selling off many new and used sweep and industrial tubes.

If you are needing anything, please email me now. I have stuff like 40KD6,
6JE6, 6JB6A, 6146, 807, 811, 866A, etc, etc.

Will trade for Centralab control stock like KB-1,2,3,4 switchcovers and
shafts, possibly other brands like Clarostat, IRC or Mallory.
