Hi. I have a Durkopp Adler 267-373 in San Francisco. Selling for an older couple who is downsizing. They bought several years ago when they started an upholstery hobby, used for a couple projects and then it sat in the corner of their living room until now. I have pictures and can send manufacturers specs. I am not a heavy material sewer (only clothes and quilts) so am not closely familiar with the machine. But we have pictures and I'll answer any questions that I can. I posted more info about the machine earlier today. Can also forward my email or phone if you want to communicate that way.
