Known as the "Featherweight". Very light weight 1/2 size straight stitch low shank machines in carrying case. Has an external motor and vertical rotary hook. The bed is not removable, as in the Class 222. Can be black (with or without decals) or colored (tan, pale turquoise, white...). Featherweight serial numbers can be usually found on the bottom of the machine, next to the bottom tray. A few of the early AD-series machines have their serial inside and underneath the bottom tray.

About the data shown here

The information here about decals is based on “Documented Machines” currently recorded in our database. We currently do not have an official Singer source about which decals were in use where, when and on which machines.

The information about factories and serials, instead, is based on the official Singer factory records that survived, plus the “Documented machines” we could verify.

Our dataset is continuously growing as new machines are documented and shared by collectors and researchers. As a result, the details presented here should be considered indicative and may be updated over time.

Contributions are very welcome: if you own or know of a vintage Singer machine, please feel free to submit information via the form or contact us to help improve and expand this research.
