Ah, would that be Sheaffer? Did you ever try their Peacock Blue ink?
No, not a Schaeffer. I do remember quite a few Schaeffers, in quite of a few fellow classmates, in high school. I, also, did see quite a few ‘blue-spotted’ shirt pockets, too.
I was one of the contrary ones, using Flair pens, when I could get away with it, except in my Russian language class, it had to be ball-point.
My usage of a fountain pen came later, in the ‘90’s, and the pen I referred to, was the Parker Vector, with a ‘fine’ nib.
Since, I have latched onto a Parker Rialto, and a ‘45’.
