After fretting that no owner manual exists online for the old Pfaff 335 I realized that there wasn't one available online for my own Durkopp Adler 205-370, either. So I scanned in my printed Durkopp Adler 204/205-370 Owner Manual and uploaded it here: http://docs.uwe.net/Durkopp Adler Owner Manual 204-370 205-370.pdf I had also found a Durkopp Adler 205-370 Service Manual in PDF format some time ago. I uploaded it here: http://docs.uwe.net/Durkopp Adler Service Manual 204-370 205-370.pdf
