These states come from the cited public evidence, not from model-code patterns. Unknown is never treated as incompatible.
Which Bobbin fits?
answered
Answerclass 15
The dated archived SINGER product page directly instructs use of Class 15 Transparent bobbins. Transparent remains a material condition; no cross-brand equivalence, dimensions, exclusivity, or material substitution is inferred.
AnswerNot established from current official evidence
Confirmed individual OEM items: 12
Example: SEW EASY FOOT
Compatible individual feet remain item-level evidence; no mount, shank, holder, adapter, or connection system is established. 12 compatible cited items remain available separately.
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.

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.
A two-hop result joins the machine’s official accessory-group membership to the OEM part matrix. Open the evidence to inspect both hops.
