Picked these up at the Washington DC Fountain Pen Supershow two weeks ago. Near the top of the 45 food chain. Harlequin family with acid etched metal finish. The only black circlet fountain pen I've handled (well known pattern, usually without the black). The other patterns are just nuts. I probably should have kept these, but perhaps having a weak moment I offered option on them to a pen friend who is more into the Parker 45 than am I. Serious eye candy.
