Thanks for all the welcomes and well-wishes. I am curious as to how Pfaff owners (of this era) use their machines to replace zippers, specifically on a moderately-thick coat. Are there adapters available, or do you simply use a proprietary Pfaff foot?
The reason I'm asking is, I don't know much about low shank feet vs. high shank (I know this is a low version), and have a couple of zipper feet (60's era) that I was hoping might work.
