If you are talking about the various Rolm 1600 series machines - there are a whole lot more of those out there. I had 12 of them in stock maybe ten years ago, and sold my last one last year. And about five years ago, I moved a few more for a client. There are also a bunch still in service at the paper mills. -- Will
