Voici un lien vers un article de 1978 décrivant l'usine Premier de Wigston :

et le passage sur le chromage :
"Premier make all their own fittings for their drums and have a new electroplating plant designed by employees. It is here that a rough looking piece of metal eventually ends up as a double tom tom holder or whatever. Each part has its own separate mould; when the part is stamped out from its mould it is trimmed of any rough edges and sent to the plating department which consists of a series of baths or dips. The parts are strung on to copper wire and sent through the various baths, the whole process taking about 10-20 minutes with the baths consisting of chemicals such as alkaline cleaner, various acids, cyanide, sodium hypochlorite, nickel, chrome, and sodium metabisulphite. When this is completed the parts are dried, checked and polished ready for assembly."
