WWI. Embroidered badge forcustoms officers, made during WWI by David company.

Specialty badges embroidered madder on a horizon blue background, 135 x40 mm, found in the stock of Éts David which closed its doors in the 1960s.
Good condition. While stocks last.
In times of war, customs were attached to the army, which is quite logical, given that their primary function is to guard the borders...
As such, customs officers were given a horizon blue uniform.
The embroidery comes in pairs, one on the right and one on the left, for each collar tab.
