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

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.
