Does anyone have some 4D22 tubes they would be willing to sell?  I need two and would take four so I have two spares. I need the 4D22 with 12v heaters, not the 4D32s. These were used by the Air Force in 1950s Cold War bomber radar systems.

Please reply directly to my email. Let me know asking price plus shipping.

Thanks in advance for any replies!
