Nomenclature<\/h3><\/span>
<\/div><\/div><\/div>\n

All primitive models 12 and 16 with the letter “e<\/strong>” have an electric motor
\nAll models with the letter “L<\/strong>” are semi-automatic machines (no automatic multiplication)
\nAll models with the letter “A<\/strong>” are fully-automatic machines
\nAll models with the letter “B<\/strong>” have technical improvements compared to the corresponding “A” model
\nAll models with the letter “T<\/strong>” have a cumulative Register (Register IV or Triplex<\/em>)
\nAll models with the letter “Z<\/strong>” have a complete capacity carry-over in the Result Register<\/em>
\nAll models with the letter “S<\/strong>” have a tabulator of 10 keys for controlling the left carriage stop
\nAll models with the letter “V<\/strong>” have a dividend set-up key, provided that they have no “T” nor “S” letter
\nAll models with the letter “G<\/strong>” have the following modernizations (mid-1950s):<\/p>\n

    \n
  1. A new bottom plate<\/li>\n
  2. A device for inverting the revolution Register<\/li>\n
  3. A new modernized keyboard<\/li>\n
  4. Always grey color<\/li>\n<\/ol>\n

    Letters are presented above in the order of priority with which the naming of machines is built.
