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.

Identity verified · evidence for each answer

Using and maintaining this machine

Check the conditions alongside each answer. Foot attachment, shank type and adapter requirements are separate; one does not establish universal accessory fit.

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.

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.
