Hi, i have just bought a pfaff 335 17B H2S , this is the manual that i have been using. Great machine, just toooooo fast, i am trying to get a servo motor for it. It uses the 134-35 needle system. At the moment i have a size 22 needle in it and using 138 size thread. My bobbin measures 22mm in diameter and 9mm wide
