In mid 1934 Parker began marking most pens and pencils with a date code, both the barrel and the nibs were marked, but lacking a date code doesn't necessarily mean that the pen was made pre-1935, since many imprints have been worn off with use. The first date codes, found for example on the Vacumatics, consists of two digits, the first one denoting the quarter of production, the second denoting the production year. Hence a "47" marking on a 1930's pen indicate that the pen was produced in the fourth quarter of 1937, not 1947, which is a common misconception
In the second quarter of 1938 this system was however changed to save production time, and a new date code, using a system of dots, was adopted. The stamp initially had three dots and for each quarter one dot was filed down leaving none for the fourth quarter. Since production was overlapping examples exist with either the imprint 28 or .8. for the the second quarter of 1938. Also, since this coding system extended over a decade, a pen marked 38 could be produced the third quarter either in 1938 or 1948.作者: 甘草 时间: 2012-11-9 12:54
