Still to confirm

An unanswered question does not mean a part is incompatible. We have not confirmed enough information to recommend it.

Presser foot — Mount or fit: Not established Full recorded limit & conditions →

Other names, regional versions, production history, further specifications and documents are not fully covered here. Their absence is not a “none exist” finding.

Next evidence targets

  • Establish exact presser-foot interface and optional-foot applicability without generic fit inference.
  • Add exact parts, service and accessory references with original scope.
  • Establish further looper, knife and stitch-configuration details from accepted model-specific evidence.

These are research questions, not claims that the missing relationship exists.
