One of these is listed for sale on the Classic Rod Forum and it is a rod design I've never seen before. Chris Carlin is an amazing rod maker so I'd expect his description on his website (see below) is very accurate. Has anyone seen or cast one of these, or even heard of it before? Are the pieces connected by a taped splice? Cool stuff...
