The spelling "ferroscyanide" doesn't exactly inspire confidence - do
you mean "ferricyanide"?
John Kiernan did a very nice review of Gallyas stains (of which there
are apparently several) on Histonet about three years ago. See
John Kiernan describes these methods as quite difficult. I have no
experience with them.
