Introduction
The world of blacksmithing tools is rich with history, craftsmanship, and sometimes confusion—especially when it comes to identifying anvils. One of the most debated and misunderstood is the Trenton 126lb Mouse Hole anvil. Is it a true Mouse Hole? Is it a hybrid? Or is the term just a nickname passed through generations?
This article provides a comprehensive and fresh perspective on identifying the Trenton 126lb Mouse Hole anvil. We go beyond common guides to explore markings, design nuances, historical overlaps, and practical tips to authenticate and evaluate these iconic tools.
What Is a Trenton 126lb Mouse Hole Anvil?
While it may sound like one distinct model, the term “Trenton 126lb Mouse Hole anvil” actually blends two separate identities:
- Trenton refers to the brand made in Columbus, Ohio by the Columbus Forge & Iron Co. (1880s–mid-1900s).
- Mouse Hole originally refers to anvils forged by M&H Armitage at Mouse Hole Forge in Sheffield, England.
The confusion arises from similar design features, age, and colloquial naming conventions used by blacksmiths and collectors.
Is It Trenton or Mouse Hole? Let’s Clarify
| Feature | Trenton Anvils | Mouse Hole Anvils |
| Country of Origin | United States (Ohio) | England (Sheffield) |
| Manufacturing Period | 1880s–1950s | ~1700s–early 1900s |
| Logo Style | Triangle stamp with “TRENTON” | Oval stamp: “M&H Armitage Mouse Hole” |
| Construction | Steel face forge-welded to iron body | Hand-forged wrought iron, steel face |
| Base Shape | Hourglass waist | Arched feet (“mouse hole” openings) |
| Typical Weight Marking | Decimal/pounds (e.g., 126) | Hundredweight system (e.g., 1-0-14) |
Conclusion: Most so-called “Trenton Mouse Hole” anvils are not English Mouse Holes but rather Trentons that resemble them in shape or wear.
Why the 126lb Weight Matters
126 pounds is considered a “sweet spot” for many blacksmiths:
- Heavy enough to absorb hammer blows efficiently.
- Light enough to be moved without machinery.
- Stable base for forging without bounce or excessive noise.
In collector terms, this weight class is highly desirable—especially when the markings are clear and the anvil is undamaged.
Key Identification Features of Trenton 126lb Anvils
To accurately identify a Trenton anvil, especially one labeled as 126lb and resembling a Mouse Hole, consider these markers:
1. Logo and Serial Number
- Look for a triangle logo with the word TRENTON stamped into the side.
- A serial number is usually located under the horn or on the underside base.
- Use blacksmith forums or historical serial charts to date the anvil.
2. Weight Stamp
- Typically found on the front foot or side of the anvil.
- May be marked as “126” or appear in a numeric format like 1-0-14 (1 hundredweight, 0 quarters, 14 pounds).
3. Shape and Features
| Feature | Description |
| Waist | Noticeable hourglass waist |
| Horn | Long, tapered, and slightly curved |
| Face | Smooth, steel-plated, with mild wear |
| Hardy Hole | Square hole for tooling attachments |
| Pritchel Hole | Round hole for punching |
| Rebound Test | Should return 80–90% of dropped ball |
Pro Tips for Advanced Identification
Some unique observations to consider (rarely covered elsewhere):
- Handling Holes: Later Trenton models sometimes have small side holes for moving the anvil—Mouse Hole models typically do not.
- Lamination Lines: Trenton anvils were forge-welded—you may notice visible weld seams or lines along the waist or face edge.
- Steel Face Check: Use a file on the edge—if it skates across, the face is hardened steel. If it bites, it may be a worn-out casting (less valuable).
Real-World Example
Case Study: A user on AnvilFire forums discovered a 126lb anvil with faint “TRENTON” lettering, a barely legible serial number, and 1-0-14 stamped on the front foot. Although initially listed as a “Mouse Hole,” it was confirmed to be a late-1800s Trenton anvil, misidentified due to its aged appearance and base style.
Market Value: What’s It Worth?
| Condition | Estimated Value Range |
| Excellent (clear marks, no damage) | $900 – $1,500+ |
| Good (visible wear, legible logo) | $600 – $900 |
| Fair (faint marks, mild chipping) | $300 – $600 |
| Poor (cracks, no markings) | <$300 |
Tip: Verify value by comparing recent sales on eBay, LiveAuctioneers, or anvil-specific Facebook groups.

Avoiding Fakes and Misidentifications
Be cautious of:
- Restamped castings sold as forged anvils
- Overrestored anvils with smoothed faces that remove valuable markings
- Sellers using “Mouse Hole” as a catch-all term
Always ask for:
- Detailed photos (logo, feet, horn, underside)
- Dimensions and weight
- Serial number (if available)
How to Restore a Trenton Anvil Safely
- Use a wire wheel or vinegar soak to remove rust.
- Avoid angle grinders on the face unless professionally restoring.
- Apply linseed oil or machine oil for protection.
- Test rebound using a 1” ball bearing drop.
Common Myths Debunked
| Myth | Truth |
| All old anvils with arched feet are Mouse Hole | False – Trentons and others share this design |
| Trenton Mouse Hole anvils are rare hybrids | Misleading – it’s often just a naming mix-up |
| Anvils lose value if used | Not always – usable condition is sometimes more valuable to smiths |
Final Thoughts: Why It Matters
Properly identifying your Trenton 126lb Mouse Hole Anvil isn’t just about assigning a name—it’s about preserving history, ensuring authenticity, and understanding craftsmanship.
Whether you’re a collector or an active smith, knowing exactly what sits on your workbench elevates both its value and your connection to it.
Frequently Asked Questions (FAQs)
Q1: Is a Trenton 126lb Mouse Hole anvil rare?
A: While 126lb Trentons are desirable, they are not exceedingly rare. Their value depends more on condition and markings than weight alone.
Q2: What does the “Mouse Hole” term really mean?
A: Originally from English anvils made by M&H Armitage, “Mouse Hole” often refers today to any anvil with similar arched features—even if made by Trenton in the U.S.
Q3: How do I verify the authenticity of my Trenton anvil?
A: Look for the triangle “TRENTON” stamp, check for a serial number under the horn, and compare the shape and construction style to known Trenton models.
Q4: What’s the best way to clean and restore an old anvil?
A: Use a wire brush or vinegar soak to remove rust, apply oil to protect the surface, and avoid grinding the face to preserve its historical value.
Q5: Where can I find the serial number on a Trenton anvil?
A: Most Trenton anvils have their serial number stamped on the underside, often just beneath the horn or on the base.
Q6: Is it okay to use a vintage Trenton anvil for modern forging?
A: Yes, as long as the face is solid and the rebound is good, a vintage Trenton can be fully functional for modern blacksmithing.
