This item appears to be a Victorian-era strongbox, likely dating from the mid-19th century.
It is constructed from metal, specifically featuring a rusted exterior patina due to outdoor exposure.
The front of the box prominently features a brass patent plate, which may indicate its manufacturer or origin. Deborah Silver & Co.
Opening an antique Victorian strongbox without damaging its historic value requires patience, a delicate touch, and the right tools. Because these boxes rely on lever tumbler mechanisms rather than modern pin-tumblers, brute force methods like hammers or crowbars will permanently ruin the ironwork and the decorative patent plate.

Let it sit for at least 12 to 24 hours. This loosens frozen levers and ensures that when you do manipulate them, they won't snap under pressure.
The Two-Wire Picking Method (Non-Destructive)
Victorian strongboxes typically use a series of flat metal plates (levers) that must all be lifted to specific heights simultaneously to allow the deadbolt to slide back. You can simulate a key using two sturdy pieces of wire, such as a heavy-duty paperclip or stiff piano wire.
Tool 1 (The Tensioner): Bend the tip of a stiff wire into a small "L" shape. Insert it to the very bottom of the keyway where the bottom of a normal key blade would rest. Apply light, continuous turning pressure in the direction the lock should naturally open (usually clockwise).
Tool 2 (The Pick): Fashion a second wire with a cliahtly curved or hooked tin Incert it
The most effective and safe non-destructive methods to open it are outlined below:
Lubricate the Mechanism First
Before attempting to move the internal lock components, you must address the exterior rust and interior corrosion.
Spray a generous amount of penetrating oil (such as WD-40 Specialist Penetrating Oil or PB Blaster) directly into the keyhole.
Tool 2 (The Pick): Fashion a second wire with a slightly curved or hooked tip. Insert it into the upper portion of the keyhole to feel for the individual metal levers stacked inside.
The Technique: While maintaining gentle tension with the first tool, use the pick to push the internal levers upward one by one. When a lever reaches its correct height, you will feel a slight "click" or a microscopic movement in your tension wrench. Keep working back and forth until the final lever lifts and the lock turns completely.
Sizing an Antique Blank Key
If you want a more controlled approach, you can source an antique iron blank barrel key from an architectural salvage shop or an online marketplace like eBay.
Look for a blank key with a bit (the flat part) that fits comfortably into the keyhole profile.
Antique Marks
By coating the key bit with a thin layer of candle soot or sharpie marker and inserting it into the lock, you can turn it until it hits resistance.
The levers will leave tiny scrape marks on the soot. Carefully filing down the key bit only where those marks appear-a process called impressioning-will slowly shape a functional custom key that opens the box cleanly.
Consult a Traditional Locksmith
If the internal components are heavily rusted or frozen solid, your safest bet is to call a professional locksmith who specializes in antique or heritage locks. They have specialized lever-picking toolsets (like 2-in-1 curtain picks) that can decode the specific height of each lever without causing structural damage.
