Hello I am hoping the experts here will recognize this. I am stumped trying to find out what military aircraft this cabin altimeter came from. I bought it because I had never seen one go beyond 50,000 feet in a jet from the early years. Now I can only think of 2 candidates that if they lost cabin pressurization would need to show up 80K but I have not seen this so far in any U2 or SR71 cockpits. Can anyone tell me what this came out of? the first is natural light. The second picture shows the bright orange color under a UV light so I assume it is radium paint.
Thanks in advance for your help.
