A few pages from a 1985 Pilot Laureate catalog/brochure — I was specifically after the “Young” model on the last page, since it’s a match for the Sharpen pencil I’ve been trying to date. This particular brochure only covers pens, but it might still help with dating some paired pencils.
I’d posted on X asking for help dating this, and @haruca_st came through with the link. Source for these images: 『パイロット ローリート 型録 ①』
Also @drifand had posted earlier that the Laureate LY-50R pen won the Good Design Award in 1984. So that should help date the matching Pencil, Sharpen HY-50R to about the same time frame.
(EDIT)
It should be noted that the complete colorway is not shown in the catalog.
Here is an image from Kelvin that shows all of them(?)
