I've been gifted with both a manual (in excellent condition) and a top-mount style treadle for a Pfaff 6 machine. Unfortunately, the machine is missing and the treadle has seen better days, but someone may be willing to do some restoration work on it if they're interested. I can post pictures if you'd like, and I can work something out for delivery. Talk to me if you're interested and we'll see what we can do!
I can mail the manual at no charge if you'd just like that. First email directly to me (this addy works) wins!
