Identity evidence only — no compatibility answer yet
The cited evidence establishes this exact machine identity. It does not establish a Bobbin system, Needle system, Presser Foot interface, OEM compatibility group, or compatible item for this exact machine.
Evidence for the name or model code is identity evidence, not parts-compatibility evidence. Facts from similarly named machines are not inherited.
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
Not established in current accepted evidence
Bobbin material and dimensions
Not established in current accepted evidence
Loading style
Not established in current accepted evidence
Bobbin case
Not established in current accepted evidence
Hook system
Not established in current accepted evidence
Important: loading style does not establish Bobbin class, hook orientation, or interchangeability.
Needle
Needle system or type
Not established in current accepted evidence
Supported sizes
Not established in current accepted evidence
Exact OEM Needle part

Needle count and insertion

Twin or special-use limits
Not established in current accepted evidence
Important: a recommendation is not an exclusive system requirement unless the OEM says so.
Presser foot
Attachment or mount
Not established in current accepted evidence
Shank or presser-bar geometry
Not established in current accepted evidence
Holder or ankle
Not established in current accepted evidence
Adapter requirement
Not established in current accepted evidence
Stitch-width and clearance limits
Not established in current accepted evidence
Dual-feed or walking-feed system
Not established in current accepted evidence
Important: a Snap-On attachment does not establish shank height, holder geometry, stitch-width family, or broad foot fitment.

Identity and compatibility badges
Identity families, physical traits, and OEM accessory groups stay separate. A group badge applies only to its named program and domains.

Temporary compatibility containment
Group-derived compatibility review in progress
Compatibility under review: Janome's 500E, MC500E, and Memory Craft 500E names resolve to this one physical machine. Its cited Category B embroidery-only membership is preserved, while group-derived accessory relationships remain withheld pending edition, domain, and condition validation. Independently cited exact-model facts are not suppressed.
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
Core answers and cited items
Machine category: Not yet established
Core domains answered: None yet
Domains with cited compatible items: None yet
Unknown is not incompatible. A missing answer means the current official evidence does not support one yet.
Identity verified; answers pending
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.
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.

Applies to: Domain not yet classified
Conditions: Category B embroidery-only membership is cited; accessory applicability remains under review pending edition, domain, and condition validation.
