I found this at a yard sale, but I have no idea what it is.
What You’re Looking At
This is a vintage “trench-style” IMCO lighter in brass, recognizable by its vented body, side ignition lever, and rugged, compact form designed for reliable use in rough conditions. The surface shows a warm aged patina, which is often considered a desirable feature by collectors.
Why It’s Called a “Trench Lighter”
“Trench lighter” is a common collector term for lighters built to be durable, wind-resistant, and easy to operate one-handed—qualities valued by soldiers and outdoor users in the early 20th century. Many of these designs use:
- Perforated/vented bodies to manage airflow
- Simple mechanical ignition systems that are easy to maintain
- Sturdy metal construction meant to survive hard knocks
Key Features of the IMCO 105/107 Style
While exact details can vary by production run and variant, IMCO trench lighters in the 105/107 family are typically appreciated for a few consistent traits:
- Brass construction with a naturally aging finish
- Lever-based ignition designed for quick spark generation
- Vented chimney/body that supports more stable flame behavior in breezy conditions
- Compact, pocketable size with a practical, tool-like feel
- Service-friendly design (often straightforward to clean and keep operational)
What “Superb Patina” Means (And Why It Matters)
Patina is the natural darkening and color shift that develops on brass over decades. Collectors often prefer it because it:
- Signals age and authenticity (when consistent and natural-looking)
- Creates a unique, one-of-a-kind finish—no two pieces age the same
- Enhances display value without needing polishing
Important Note: Aggressive polishing can remove character and sometimes reduce collector appeal. Many collectors consider original, untouched patina a premium trait.
Condition Highlights That Affect Value and Desirability
When people describe a lighter as “working great,” they usually mean it reliably performs core functions. For collectors, these points are especially important:
- Ignition reliability: produces sparks consistently
- Mechanical integrity: lever action feels firm and not loose or wobbly
- Body condition: no major dents, cracks, or missing parts
- Originality: fewer replaced components often increases interest
- Fit and finish: components align well; cap and housing sit correctly
How These Vintage IMCO Lighters Typically Work (High-Level)
Most trench lighters of this type operate with a simple sequence:
- A lever action drives a mechanism that creates a spark.
- The flame is sustained by a fuel-soaked internal material (typical of classic liquid-fuel lighters).
- The vented upper section helps the flame stay stable and protected during use.
This is a mechanical, pre-electronic design—part of why it remains popular with collectors.
Authentication and Identification Tips (What to Look For)
If you want to confirm model family and authenticity, collectors typically check:
- Stamped markings (brand, country, or model references)
- Build quality and machining (clean fits, consistent perforations, solid hinge/lever hardware)
- Design consistency with known IMCO trench-lighter layouts
- Wear pattern realism: natural handling wear usually appears on high-contact points (edges, lever areas)
Care, Preservation, and Display Tips
To keep a vintage brass lighter looking good and functioning well (without damaging value):
- Store dry to avoid corrosion or green verdigris buildup
- Avoid harsh metal polishes if you want to preserve patina
- Use a soft cloth for dust and fingerprints
- Keep it away from extreme heat and direct sun for long periods
- If displaying, consider a small stand so it doesn’t roll or scratch surfaces
Safety Basics (Important)
Vintage lighters are functional mechanical devices, but they can also be hazardous if mishandled. Keep these points in mind:
- Treat it as a flammable-fuel item if it is fueled
- Keep it away from children, heat sources, and open flames
- If you notice leaks, unusual odors, or damaged seals, do not use it
Why Collectors Still Want IMCO Trench Lighters
Collectors often describe these pieces as the perfect mix of history, engineering, and everyday-object charm:
- Historic “WWI–WWII era” association (style and lineage)
- Mechanical simplicity that feels satisfying to operate
- Brass aesthetics that age beautifully
- Practical, durable design compared with many modern novelty lighters
Conclusion
A brass IMCO 105/107 trench-style lighter with superb patina and strong working condition stands out as both a functional antique tool and a collectible object. Its appeal is not only in lighting ability, but in the combination of rugged engineering, period design, and authentic aging that makes each example visually and mechanically distinctive.
