The best I can do quickly is to give you a link to the blog page where I rewired a Pfaff 130 w/coffee grinder back in April. (I have 4 followers - no ads - not for money) You can the pic
here. The second photo shows part of the original bracket. I should say, however, that most normal "L" brackets will work, I have a 1.5 amp motor and bracket from an old Wards machine on my Pfaff model 30. The 130 mounting lug will accept many other makers brackets.
