Key points
- Identify the exact model first, then look for the Singer (Simanco) part number.
- Bobbin cases, slide plates and the right bobbins are the most-missed parts.
- Belts and motor belts are sized by model and handwheel.
- Original Singer parts are stamped SIMANCO; ISMACS notes 20th-century Singer parts are sought after.
Before buyingIdentify the model and part number
Use our model identifier and serial lookup. Then find the Singer part number, from the parts list for your model, the part itself (Singer stamped “SIMANCO” on many) or a supplier’s cross-reference. Many parts are shared within a class (all 15s, all 66/99s, all slant-needles) but not across classes.

Original or newOriginal or reproduction parts?
Reproduction belts, needles, bobbins, feet and cords work well. Bobbin cases and hooks are more critical: one buying guide notes replacement bobbin cases may not produce as good a stitch as the original. For value, original decorated parts (slide plates, faceplates, handwheels) matter; ISMACS says bedslides, cams and wheels from 20th-century Singers are especially sought after.
WhereWhere to find vintage Singer parts
Specialist vintage-sewing suppliers, sewing-machine repair shops, online auctions (search by part number) and parts machines: a non-working machine of the same class is often the cheapest source of small original parts.
