Here is a nice vacuum tube: ER56, Eveready Raytheon, 4-pillar radio tube. It looks like a triode with cathode. See pictures. Looking in RM it is not founded.

ER is often found as a prefix for Eveready-Raytheon tubes. Yours is just  the same as a common 56.

It looks different and it is from an other manufacturer. Where to upload?

Dear Francisc
Nice that you have asked. In the meantime Konrad has installed the ER56 and we would be glad if you upload your photos to the tube.
Cordially,

Ernest
