Differences in these two Singer presser feet? 161612 vs. 161455
I'm looking at a Singer "Special Purpose" presser foot. I have found two that match the illustration in the 1971 version of the Instructions Manual for my Fashion Mate 252.
One is Singer # 161612; the other is Singer # 161455.
For the life of me I can see only one difference...
The line drawing in the 1971 Instruction Manual shows the side view of the attachment section makes an almost 45-degree angle from the back edge toward the ankle section of the 161612.
A photo of the 161455 on eBay shows this same 45-degree angle making a 90-degree turn before morphing into the angle section.
I don't know if I can copy the photo here.
Do you know of any differences in these two feet? Both are listed as "Special Purpose" with their respective numbers.
