A Japanese collector I follow on X (@IrNoak)
posted a haul of stationary items they had recently acquired. Laying in the image was a Pilot catalog from 1995. I reached out to them and asked for some pictures and here they are. I was happy to see this as it has the H-109x and H-56x listed so now I have an earlier datapoint – my notes had 1997.
Many pencils listed but here are some that caught my attention. I am really grateful to @IrNoak as this is the only catalog I have seen here on Knockology that had the H-109x and H-56x listed.
Further confirmation that the fabled 1988 discontinuation year of the H-300x models was false.
I’m going to update those earlier images I presented in the double-knock topic with a table of dates, because it’s just faulty information and I don’t want to keep spreading the wrong info.
Yes, I’ve listed some information here, I believe they’re still credible.
And of course, there’re multiple model numbers for one single pen, but personally I don’t have much interset on studying the variation of model numbers.
