请教51达人---关于双珠尾环规格

yexihuan

最近陆续收了几支51,很幸运品相都还不错.手握51,感慨70年前极具前瞻性的设计,即使放在今天看,依然像是当代工业品一样...

问题来了,发现手里两支分别产于42年和46年的美产双珠尾环规格不大一样,芥末那支尾环直径很大,但是与笔杆衔接部位的直径又是一样的,有图片为证,非常明显.(我个人喜欢宽环滴,大气 )
查了查资料,可能是我看的不细并没有找到关于此类问题的描述.
这个到底与年代有关,还是与产地分厂不同有关?
对于51我是大菜鸟,请达人不吝赐教...

    其实学名是yellowstone,不过,芥末也挺不错...

拿到实物,给我的印象就是,细腻的像糖糖,很想舔舔

这种批次差别是很正常的，根据观察，早期许多顶圈和尾圈的高度要比后期略大。这些细节问题资料上是不会提及 ...

  兄好眼力,  的确不是一套,芥末是单笔.

另一个是buckskin铅笔,heritage series,14K trim和笔嘴.

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.

In 1950 a new system for the date coding was introduced where the two digits only indicated the year, not the quarter hence "50" means made in 1950, this system was used in the US until 1955 and in Canada a few years longer..

    这个资料不错.但是没有提到我问的问题,

哎 也没必要较真,生产这些年的量产笔肯定不止一套模具的,let it go
