The brand is changed into Common production France because this tube is sold under the Mazda, Metal, Cyrnos and Eta brand.

The ETA brand, from 1931 on.
The Electrical Trading Association Ltd
Aldwych House, Aldwych,
London WC2
This company imported Mètal/Mazda (French) tubes but used there own ETA brand, but the type numbering is from Mètal/Mazda. The UNIS FRANCE logo on tubes and boxes proves that they are really made in France.

Datasheet atteched.
