Dynaco Marked Tube EL34

[Rudes]

Hey Guys, I have a set of EL34 tubes that are marked Dynaco Gt Britain. They do not appear to be Mullard. They do not have the Mullard codes and no hole in the alignment stem. They have a code 922-107 on them and have a brown base with two large halo getters.

Looks like Tesla.
Brown base, silver tabs under the anode, slight dark rainbow getter.

From everything I've seen on line, would indicate Tesla. Why would it say Gt Britain on it?

In those days relabeling was very common, particularly with tubes made in the communist bloc. (Eastern Europe)
