Key points
- Red Eye is a decal, not a model: it is best known on the US-made Singer 66.
- The 66 is full size (about 30 lb); the 99, from 1911, is a 3/4-size version weighing about 22 lb.
- Both use a drop-in Class 66 bobbin and 15x1 needles.
- Early 66s used back-clamping presser feet; later ones use standard side-clamping low-shank feet.
The nameWhat is a Singer Red Eye?
Singer decorated its japanned machines with transfer decals, and collectors name machines after them. The “Red Eye” pattern has a pair of red, eye-shaped motifs among gold scrolls. singersewinginfo calls the American Red Eye 66 “a very colourful machine”, and ISMACS shows an example made in the 1920s. Our decal guide has a section on it.

singersewinginfo says the 99 has an identical mechanism to the 66 and shares many parts other than the body casting. The quickest test is size: measure the bed. See our model pages for the 66 and 99.
FeetBack-clamping presser feet on early 66s
Early Model 66 machines used back-clamping presser feet, which attach to the back of the presser bar. Modern low-shank feet clamp from the side, so check which kind your machine has before buying attachments. See vintage Singer presser feet.
DatingHow old is my Red Eye Singer?
Use the serial number on the bed: our lookup gives the year it was allotted and the factory. Decal dates are approximate because Singer reused patterns for years.
