cited identity · physical identity not yet accepted
What is actually verified
Cited machine label — physical identity not yet accepted
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
Reviewed answers at a glance
These states come from the cited public evidence, not from model-code patterns. Unknown is never treated as incompatible.
Which Bobbin fits?
Not yet reviewed
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.
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.
Bobbin
Bobbin class or system
Not established in current accepted evidence
Exact OEM Bobbin part

Important: loading style does not establish Bobbin class, hook orientation, or interchangeability.
Needle

Important: a recommendation is not an exclusive system requirement unless the OEM says so.
Unknown is not incompatible. A missing answer means the current official evidence does not support one yet.
Specifications
Documented machine facts
Multiple cited representations for one field share one row. SewGraph preserves every value and exact proof passage; it does not guess which representation is “raw” or “normalized” when the public projection does not label that distinction.
Group codes are namespaced to the issuing OEM program and apply only to the cited domains. They are not machine series and do not prove compatibility outside those domains.
Open the exact OEM PDF page or captured HTML edition when a safe destination exists; otherwise SewGraph labels the OEM support-page fallback honestly.

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.
Compatibility proof passages: 0. The passages below support identity facts only.
