Cloffe, this from a Booklet AyA sent me when I ordered some spares.
It is called "Spanish Treasure" by Terry Wieland and has an introduction
by Michael McIntosh:
Serial numbers.
"The numbers assigned since 1945 are:
1945 to 1948 ---- 0001 to 19,999....
1994 -----602,423 to 602,642"
The serial numbering changes starting 1995; they are in the form of
16-03-001-95 to 16-03-800-95
You can see from this that they have made over 600,000 guns.
Date codes.
The list from the "personales" website is the same as the one published
in the referred booklet. When the Banco de Pruebas de Eibar starts using
a letter and number (1956-A1) they do not use "LL" or "RR" but they do use
an N with ~ on top. So A1 is 1956 and Z1 is 1980. Then A2 is 1981 and S2 is 2000
There is a note that says that the codes from 1995 onward were assigned
but never used (?).

P.S. On all the Spanish guns I have (4) the date codes are on the barrels.
