Please help me to identify this very old tube
I have the attached tube. It looks very old. There isn't any sign on it. It's a triode. The base looks UV. I think it's manufactured by Moorhead, but I'm not sure. Has anybody idea about it's manufacturer and/or type?

it seems to be an Electron Relay from de Forest or Marconi - Marconi has an rubber-stamped on base - like Your tube.

Thank you for your effort. It looks the closest I have ever seen.
