I have a pfaff 1217-19. I love it. model before the 1222 with computer. I would check with Brubaker in Pa.
https://brubakerssewing.com/ Great people and works on Pfaff machines. They have refurbished ones and sooooo helpful, even try to help you over the phone fix your problem so you don't have to ship it to them. I had to send mine because it needed a new bushing......
