The typical “European”
specifications for a needle includes a word, a number (usually a four digit number) and a final combination of letters and numbers. For example: Vota 78.60 G.02 The capital letter at
the beginning of the word ( “V”), identifies the origin of the needle (obtained from a wire, pressed or die-cut), the type, the number
of butts and the type of tail. The other capital letters have a very precise
meaning, except for the vowels “e” and “a” which are added to make the word pronounceable, and indicate the shape and the
height of the butt, the eventual existence of a groove and its size, the
length of the tail and some other features of the
needle.

The next group of
numbers identifies the needle according to the length and the gauge. The first
part indicates the whole length rounded off to the mm (in our case that makes
78 mm); the second part indicates the gauge of the needle in hundredths of
millimetres (in our case the gauge of the needle is equal to 0.60 mm).
The final group of
letters and numbers has to be read as follows. The first capital letter
indicates the needle manufacturer (For example Z for Torrington, E for Exeltor,
G for Groz-Beckert). The next number is used to distinguish a specific needle
among all the needles produced by the same manufacturer.
The next letter refers
to some particular features of the needle: for some needles an “A” indicates
that the latch has been fixed with an angular pressed pin while an “R” means
that the latch has been fixed with a straight pressed pin. For other needles,
the latch fixing method is indicated by a “0” before the last number. A “0”
indicates that the latch has been fixed with a standard pressed pin; no “0”
means that the latch has been fixed with a screw pin.
