Hi Mauricio
I think perhaps we are running into a language barrier here. I don't understand what you mean by "termination of transformers" or the word "barniz."
So please allow me to run my previous post through Altavista's Babel Fish - be warned, however, that this may not translate exactly right!
El ajuste y los bordes habrÃan sido acabados originalmente con la laca negra. El resto del gabinete habrÃa sido rociado con el equivalente de la nuez media de hoy que entona la laca. Creo que el ajuste negro habrÃa sido hecho DESPUÃS DE QUE el gabinete fuera rociado con la nuez media.
The above paragraph was translated with Altavista Babel Fish:

And if it did not translate correctly, blame them, not me.
I do not speak Spanish. But I hope this will be helpful to you.
I think perhaps you may be asking if the black trim was sprayed on with the same paint used to paint Philco transformers? Perhaps. But I feel you should not mix enamel and lacquer on the same cabinet.
Having also addressed this in another thread, I'm locking this one.
