I came across a tweet with a photo of a (late-70’s???) catalog page of Pentel pencils.
I have saved the page into my Catalog directory (Dropbox - Pentel Catalogs - Simplify your life) as <Pentel of Japan 1978 + or - (single page).jpg>.
What interests me about this is the picture shows the 5 P1075 colors, then what is clearly a P875, an S55, ML5, ML51 and then a P505. Below that is text with names (that match those at the top of the page). The first one is , then P805, then 5, then Middle 5 and last Short 5.
The last 3 names have long been known to be in common use, but this is the first time I have seen Iris connected to the P1075, and this is the first time I have seen a definitive name for the “P875”, which we got from a Yahoo Auction, and went along with, because it made sense.
I will be changing the next version of the Pentel book to update the P875 to P805, with an explanation of the reason for the number change, and I will be adding the name Iris to the P1075.
