Good eye, I don't think I'd have picked that one as brilliant chartreuse from the group pic. Sadly, in a fit of stupidity and because I had others on the way, I sold that one to a friend who'd been looking for another Roxie. It actually looks more like this, like you said one of the most unique colors I've ever seen on a guitar. I'm also partial to their ocean spray and leopard finishes, very unique ... probably with good reason.
Jack - Yes, one and the same. I've liked Hamers for years but don't know enough about them, I mostly lurk here to pick up a few tidbits.
