I work mostly on English saddlery. I just happened upon this machine and thought I would replace zippers in tall English riding boots. So I mostly look at it lol. I will oil and run it to keep it moving. I am kind of a sewing machine junky. Can't help it, that's why I have had several Singer patchers come through my shop. I like cleaning them up and get them running again. The Adler was mint and all I did was change the motor to a servo and add a speed reducer.
