I just went back to this topic after almost seven years to notice that there are some questions left.

The Edison 2min Mexican box indeed has it's own form number which interestingly is also written in Spanish language. I attach a photo of it.
I have a question to "Valecnik" about the Bohemian series. You write that the label on lid is written in Czech. Do you mean the title information or the entire label (what usually is "Edison Gold Moulded Records - This record should run at 160 revolutions per minute (not faster)". All European non-British/French/German series' boxes that I ever saw had either the text in English, French or German but never in the language of the series (Czech, Norwegian etc.).
