S.E.L.E.Z.

Also SELEZ (Sociedad Española de Lámparas Eléctricas “Z”) - sometimes written just as Lamparas "Z" S.A.
Spanish manufacturing company founded by Philips in 1908 first to make light bulbs and later all the components used by Philips in Spain.
According to the runout used, and the labels involved, S.E.L.E.Z. seems related with Fonogram, S.A. and later COFASA.
Lacquer cuts are identifiable by 850, same as previously on Lamparas "Z" S.A. and on later on Fonogram S.A. (and COFASA and PolyGram Servicios, S.A.).
Please don't use 850 to add lacquer when other of theses companies are credited as manufacturers.
