Waterman Mysterious Blue, Parker Quink Permanent Blue/Black: The Same Ink or Not?

[Foyle]

I've read in various places that these two inks are actually the same ink in different bottles. Does anyone have an opinion on this? The color does seem awfully similar between the two, but Parker is cheaper by volume than Waterman making it the better buy–if indeed they are the same ink.

What say you?

If it walks,looks and wacks like a duck maybe it's a duck.

I haven't used either, but don't believe that they are. JMO however.

I say no. Different inks completely. Maybe similar in color, but that's all.
