I am trying to find a tension cup for an old Pfaff machine, model 230. I have searched the internet and have yet to come up with a source for this old part. Does anyone have any ideas I can pursue? Sure would like to use this machine.

How about calling pfaff or emailing them?
my only suggestion

or take it to a sewing machine repair place

Sent you a PM

There is a vintage Pfaff group on Yahoo, I think. That type of group often is knowledgeable about resources for parts.

Try this site. I have found many parts for different machines. You may be able to contact them too.. Good Luck!!!
