Compatibility first
These states come from the cited public evidence, not from model-code patterns. Unknown is never treated as incompatible.
AnswerNot established from current official evidence
Confirmed individual OEM items: 1
Example: Metal Bobbins - Type L
The core bobbin system was not established; loading words or accessories are insufficient. 1 compatible cited items remain available separately.
none · 1 relationships · 0 cited system traits · 0 cited recommendations
AnswerNot established from current official evidence
The ordinary needle system was not established; compatible accessories cannot substitute for it.

AnswerConnection not established from current official evidence
Confirmed individual OEM items: 2
Example: Master Shank
The dossier review confirms these specific compatible items. It does not establish the machine's general mount or 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.
Cited machine facets
Identity families, physical traits, and OEM accessory groups stay separate. A group badge applies only to its named program and domains.
Temporary compatibility containment
Compatibility under review: this OEM Group I roster membership is preserved, but SewGraph has temporarily withheld group-derived part claims because required master-shank conditions were lost in the earlier projection. Independently cited exact-model parts remain available.
Verified identity facts, cited machine traits, and independently cited exact-model relationships remain available. The held OEM roster group is shown as evidence only and currently asserts no public compatibility domain.

Evidence coverage
Machine category: Not yet established
Core domains answered: None yet
Domains with cited compatible items: bobbin (1), presser foot (2)
Unknown is not incompatible. A missing answer means the current official evidence does not support one yet.
Parts & accessories
A two-hop result joins the machine’s official accessory-group membership to the OEM part matrix. Open the evidence to inspect both hops.

OEM compatibility programs
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.

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.
Supported public fields (7): machine type, model codes, oem program groups, part relationships, physical identity, preferred official name, presser foot
Unresolved fields (6): aliases, bobbin, lifecycle market, needle, product line, series
Review controls checked (2): source documents and publication/conflict handling are process receipts, not additional machine facts.
Review pass complete — not “all known.” Every tracked field has a recorded disposition; the unresolved fields above remain unknown.
