cited identity · physical identity not yet accepted
What is actually verified
The official evidence supports the displayed name or model label. SewGraph has not yet accepted one exact physical-machine entity for this route, so no compatibility answer is attached.
A cited label is not proof that similarly named, regional, revised, or same-code machines are physically identical.
Compatibility first
These states come from the cited public evidence, not from model-code patterns. Unknown is never treated as incompatible.
AnswerNot reviewed yet
This core system has not yet received an explicit dossier review. Compatible cited items are listed separately and do not establish the system.

Compatibility field map
A core answer does not complete every physical axis. Each field below is shown only when current accepted OEM evidence establishes it; all other axes remain explicitly unestablished.
Important: loading style does not establish Bobbin class, hook orientation, or interchangeability.
Important: a recommendation is not an exclusive system requirement unless the OEM says so.
Important: a Snap-On attachment does not establish shank height, holder geometry, stitch-width family, or broad foot fitment.

Unknown is not incompatible. A missing answer means the current official evidence does not support one yet.
This machine is included because its exact identity is cited in an official OEM document. We are not publishing specifications or compatibility until those claims clear the same evidence gates.

Every passage below says exactly what visible fact it proves. Repeated references to the same locator are counted once; identity evidence never counts as compatibility evidence.

Evidence review status
Dossier review completion means every tracked facet received a disposition; it does not mean every machine fact or compatibility axis is known.
