Janey, thank you sooo much for the Pfaff links and all of the information you shared with me! I searched most of the evening last night and wasn't able to find anything, not even a picture, of this machine. I have fiddled some with the tension and it looks better but still not perfect.
I was surprised to find out that this machine could have been a treadle even though it came in a case similar to a suitcase. The extra thingy on the front of the machine looks like another tension disc.
Again I'm grateful for the information, thank you very much!
Jan
