Well ink loving friends, here is a review of some vintage Sheaffer's Skrip Permanent Blue Black with RC-35! There are some older reviews on our site, but not many. Let me share the story of my acquisition.
Attending a preview for a living auction of someone in our area moving to an assisted living in Florida, I discovered a secretary's desk. It had been repainted a muted green, though I fail to understand the mentality that wishes to cover beautiful old, dark wood. The auctioneers weren't going to bother offering the contents separately, so near the end of the long day it came for sale. The desk itself was neat, but the contents were even better: some old pens, dip pens and nibs, other knick-knacks and bric-a-brac, and a bottle of Sheaffer Skrip ink.
From a bit of research on the site this bottle comes from the era 1955-67. It was made in Ft. Madison while the Snorkel pen was on the market. It's somewhat easy here to find old bottles, less so with liquid ink in them. This ink was perfectly clear, still had a good inky aroma. In working on a project with my inks, I filled an Edison Beaumont pneumatic filler with this one. Here are the results.
The images seem to have captured the ink as darker than in fact. This is not the darkest of the modern blue-black inks, it is lighter than most, but not light itself, if that makes sense. BB4B, OS Manganese, Sailor Shoushikan Sei-ran, and others are all darker overall than this ink. But these other inks don't have quite the same kind of shading as this one which ranges from fairly light to quite dark. Another review shows this ink as being much darker. But I can't elaborate on the provenance of this particular bottle other than what I have.
I haven't experienced any problems with this ink. It is actually quite water resistant, so while it is said you can recover your writing under UV light if the ink is washed away, at least on the modern inkjet paper it was quite permanent.
A nice trip down memory lane.
