Dat zou zomaar kunnen.
Het Radiomuseum zegt dit over de merknaam Ultron:

Name: Ultron (tubes) (B)
Abbreviation: ultron
Products: Tube manufacturer
Summary:

Ultron, (MBLE)

Nicht zu verwechseln mit der Nachkriegs-Marke von Bürklin OHG bzw. ULTRON-Elektronik GmbH, 80336 München, Deutschland. Diese neueren Ultron-Röhren sind Handelsware von verschiedenen Herstellern in Ultron-Schachteln über Bürklin verkauft.
History:
Before WWII the “Ultron” brand name has belonged to the “Manufacture Belge de Lampes Électroniqiues”, or in short “MBLE”.
MBLE used the brand name “Ultron” for European type tubes, for American type tubes they used the brand name “Adzam”, as well they used the brand name “Mazda” for lighting bulbs.
Apparently, after WWII they dropped the “Ultron” brand and henceforth they used the brand name “Adzam” for any tubes.

Later on, the German electronic distributor Bürklin took the brand name “Ultron” for the tubes they sold as reseller.
