Reeves is a Canadian company I remember best for making oil pastels I regularly destroyed as a child in unthinking opposition to my mother’s artistic efforts, and which if it still exists apparently specializes in finger-printing ink (Google offers little encouragement). Back in the day, it seems that they made ink, and as I stumbled into ownership of a quart of the stuff, I add it here.
Blue-black: An old-school reactive blue black, and like Waterman and the modern Lamy expressions of the same thing, some of the active ingredient precipitates out of solution over time. When it was fresh and being tipped into the desk-wells in schools, this would have ended up as quite a dark ink indeed.
