Pete Sacopulos recently had a quite nice PENnant article on Chameleon, a fountain pen company whose product has quite low prevalence today. I wish he'd given me a yell before the article, as he knows I have one not in his image bank, but it wasn't meant to be this time. Chameleon pens are double nib pens, with nib unit each at end of the pen, though usually with just one clip. One of my grand lucky finds several years ago on ebay was a superb Chameleon, the only example of this brand I own (though I've photographed a few). This one also has excellent preservation of the Jade color, which- as many of you know- qualifies it for my Jade pen collection. And, before ya ask, rights of first and second refusal for this one have been claimed. Chameleon falls into the perhaps ill-defined category of
High Quality, Small Make, Frankly Weird Pen. I suppose Pullman, Colorado and others are part of the cluster.
This is the only Jade Chameleon I've seen. Unlike most, it has clips at both ends. Later I will post more photos to flesh out the eye-candy profile. Let's start with a simple closed shot, next to a well known oversized pen, a 5.5" Waterman 56 in Cardinal Hard Rubber.
