I made a video of it sewing. If you have never had an Adler, they are a real treat. They are known as the Cadillac of industrial sewing machines.
Once you get one, you know why. The cast iron is heavy and very nicely machined. I have another Adler and a couple Pfaff's and the Adlers stand above the Pfaffs when it comes to quality. This is a German made machine.
I'd guess mid-70's. As you can see from the photos it doesn't have much wear. I have a van with a lift gate so I may be able to deliver it as well, depending on where you are. The machine is in Northern Indiana, just northeast of Fort Wayne.
