Original Singer Bobbin Winder - Model 66K Lotus Complete Assembly

Complete original Singer bobbin winder assembly for the iconic Model 66K "Lotus" machines manufactured in Scotland between approximately 1900 and the late 1920s. This is a complete assembly including the handwheel guard with authentic Lotus decals, not just the winder mechanism alone.

What's Included - Complete Assembly

• Bobbin Winder Mechanism: Complete working unit with high-mounted design
• Handwheel Guard: Original guard featuring the iconic Lotus decals in gold, green, orange, and dark red
• Three (3) Tension Springs: All springs present and working properly
• Large Knurled Hub: Designed for direct treadle belt drive (no rubber friction tire)
• Freed Mechanism: Internal gears freed and working smoothly (not frozen from dried oil)

About the Lotus Model 66K

The "Lotus" decals (also known as "Egyptian" or "Thistle" pattern) are widely considered one of Singer's most beautiful and intricate decal sets. While "Red Eye" decals dominated the American market, the Lotus design was the standard for machines sold in the UK and Europe.

• Production Period: Approximately 1900-late 1920s
• Manufacturing: Clydebank factory, Scotland (denoted by "K" in model number, e.g., 66K)
• Decal Style: Lotus pattern - stylized lotus flowers with Art Nouveau and Art Deco influences
• Colors: Gold gilding with accents of green, orange, and dark red
• Market: UK and European models
• Early Versions: May feature small red tips on the flowers (pre-1920)

High-Mounted Treadle Design

This bobbin winder features the high-mounted design used on Scottish-made Model 66K treadle machines. It combines the belt-driven treadle operation with compatibility for 6-spoke handwheels.

• Large Knurled Hub: Designed to catch the moving leather treadle belt directly (no rubber friction tire needed)
• Direct Belt Drive: Powered by the treadle belt rather than contact with the handwheel
• 6-Spoke Handwheel Compatibility: Designed to work with 6-spoke balance wheels
• High-Mounted Position: Mounted higher on the machine's pillar for proper belt alignment
• Automatic Stop: When functioning correctly, the stop latch automatically disengages the mechanism when the bobbin is full

Why This Assembly is Special

• Complete with Lotus Guard: Finding a complete assembly with the original handwheel guard featuring authentic Lotus decals is increasingly rare - these Art Nouveau designs are highly collectible
• All Three Springs Present: Many vintage units are missing springs or have springs that have lost tension - this unit has all three working properly
• Belt-Driven Design: The large knurled hub is specific to treadle models and eliminates the need for a rubber friction tire
• Freed Mechanism: The internal gears frequently become frozen from dried oil after 100+ years - this unit has been freed and works smoothly
• Scottish Craftsmanship: Clydebank-made Singer machines are prized for their quality and the beautiful Lotus decals

Compatibility

Complete Assembly Fits:

• Singer Model 66K with Lotus decals (circa 1900-late 1920s)

Related Models: The Lotus decal pattern also appeared on Model 66K-2 (Family Model) and 66K-3 (Hand Crank) variants, though this assembly is specifically designed for the treadle-driven 66K-1.

Condition Grading System

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

• 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 and a freed, working mechanism.

Installation & Care

The assembly mounts to the machine's pillar in the high-mounted position. Proper alignment is critical so the large hub engages the treadle belt correctly. Apply a drop of sewing machine oil to the internal gears periodically, and handle the Lotus decals with care - these Art Nouveau designs are irreplaceable and highly collectible.
