Siemens tubes always have the "Made in Germany" marking, on E93CC it should be on the rear ... can't see it on your specimen ...

Couple of each. I think the lack of gold pins points to E283CC.

A legérdekesebb dolog, amit eddig találtam, az az azonosság a TFK ECC801S gettertartóval.
A TFK gyártotta a Siemens számára, vagy fordítva, a Siemens a Telefunken számára.
E283CC tubes excluded, pin9 is not shielding, but central heating
