Original Singer Bobbin Winder - Model 66 Red Eye Complete Assembly

Complete original Singer bobbin winder assembly for the iconic Model 66 "Red Eye" (Scroll) machines manufactured in the USA between 1902 and 1923. This is a complete assembly including the handwheel guard with authentic Red Eye decals, not just the winder mechanism alone.

What's Included - Complete Assembly

• Bobbin Winder Mechanism: Complete working unit with heart-shaped cam level-wind system
• Handwheel Guard: Original guard featuring the iconic Red Eye (Scroll) decals in red and gold
• Three (3) Tension Springs: All springs present and working properly
• New Friction Tire: Fresh rubber tire for reliable engagement
• Freed Mechanism: Worm gear assembly freed and working (not frozen from dried oil)

About the Red Eye Model 66

The "Red Eye" (officially called "Scroll (red)") is the most iconic and collectible decal variant of the Singer Model 66. This distinctive design features a large circular "eye" motif in red and gold.

• Production Period: 1902-1923
• Manufacturing: USA-made by Singer Manufacturing Company (SIMANCO)
• Machine Type: Full-size Model 66 treadle and hand crank machines

The Heart-Shaped Cam Mechanism

What sets the early Model 66 Red Eye bobbin winder apart is its sophisticated "heart-shaped cam" system. Unlike modern winders where you guide the thread with your finger, the heart-shaped cam automatically moves a thread-guiding "finger" back and forth, laying thread in perfectly flat, even rows across the bobbin - just like professional industrial machines.

Why This Assembly is Special

• Complete with Red Eye Guard: Finding a complete assembly with original handwheel guard and authentic Red Eye decals is increasingly rare
• All Three Springs Present: Many vintage units are missing springs or have weak springs - this unit has all three working properly
• New Friction Tire: Fresh rubber tire installed (originals are usually dried and cracked)
• Freed Mechanism: Internal worm gears freed and working smoothly (commonly frozen on century-old machines)

Compatibility

Complete Assembly Fits: Singer Model 66 with Red Eye (Scroll) decals (1902-1923), USA-made full-size Model 66 treadle machines with spoked handwheels.

Note: While this complete assembly is specific to Red Eye Model 66 machines (due to the decorated guard), the bobbin winder mechanism itself is compatible with several other vintage Singer models.

Condition Grading System

Since these are vintage original parts over 100 years old, condition varies. Select the grade that matches your restoration needs:

Grade A - Excellent Condition:

• Minimal wear and patina
• Red Eye decals largely intact with vibrant color
• Little to no rust or pitting
• All three springs strong and functional
• Mechanism moves freely and smoothly
• Ready to install and use immediately
• Best choice for museum-quality restorations

Grade B - Very Good Condition:

• Light to moderate patina consistent with age
• Red Eye decals present with some fading or minor wear
• Some surface rust or light pitting possible
• All three springs present and functional
• Mechanism freed and working properly
• May benefit from light cleaning or polishing
• Great choice for working restorations

Grade C - Good Condition:

• Moderate to heavy patina, authentic vintage character
• Red Eye decals may show significant fading, wear, or partial loss
• Visible rust, pitting, or paint loss on metal components
• All three springs present and functional
• Mechanism freed and working
• May require cleaning or touch-up for best appearance
• Budget-friendly option for machines that need a working winder

All grades are fully functional. The grading reflects cosmetic condition only. Every assembly includes all three springs, new friction tire, and a freed, working mechanism.

Installation & Care

The assembly mounts to the top of the machine bed near the handwheel. Proper alignment is critical for smooth operation. Apply a drop of sewing machine oil to the worm gear mechanism periodically, and handle the Red Eye decals with care - they're irreplaceable.
