These are old production Shuguang 805 FU-5M thick getter version.
I have few boxes of 10 pcs 805 FU-5M. These are fine 805 tubes made for export.
All pairs I have listed for sale are really perfectly matched with exact or almost exact parameters due to factory matching and my personal testing on Neuberger RPM370 tester with 600V on plates.
79 euros for pair
