Original Early Non-Numbered Upper Tension Assembly for Singer 221 Featherweight
Style: Early Non-Numbered (1933–1937)
Condition: Original — complete assembly, excellent condition
About This Part
This is a genuine original early non-numbered upper thread tension assembly for the Singer 221 Featherweight — the rarer of the two tension styles found on the Featherweight. This style was used on the earliest Featherweights produced from 1933 to 1937 and features no numerical markings on the adjustment knob. Tension is set by feel and stitch appearance rather than a numbered dial.
Unlike the later numbered dial assembly (#45871), this early style uses a visible exterior coiled tension spring and a simpler thumb nut design. The tension stud (post) on these early machines is also slightly different from later models.
Complete original assemblies in excellent condition are increasingly rare and highly sought after by collectors and restorers looking to maintain historical accuracy on their early Featherweights.
Details
- ✅ Original part — not a reproduction
- ✅ Complete assembly — all components present
- ✅ Excellent condition
- ✅ Early non-numbered style — no dial markings; tension set by feel
- ✅ Exterior coiled tension spring — correct for 1933–1937 Featherweights
Important Restoration Note
This early non-numbered assembly is physically interchangeable with the later numbered dial style, but the tension stud (post) differs between the two styles. If you are restoring an early Featherweight for historical accuracy, this is the correct assembly. Most experts recommend retaining the original non-numbered unit on early machines for collector value.
