Datation of Japanese Pens. VII. Sailor's Nibs (II)

Some years ago I spoke about dating marks on Sailor nibs: up to 2016, the manufacturing date on Sailor nibs was encoded in the form

abb

where a was the last digit of the year, and bb was the ordinal of the month: 01 for January, 02 for February, and so on.

710. On this case, October of 1957.

212. December of 1982? Maybe 1972?

Starting at some point in 2017, Sailor changed this code for another one in the form

ccX

Now, cc are the two last digits of the year, and X is a letter that encodes the month of production in the form A for January, B for February, and so on until L for December.

17K: November of 2017.

And now, the former ambiguities (does this 9 mean 1979, 1989 or 1999?) are eliminated.
