Description

Uberti 1851 Navy London — .36 Caliber Percussion, 7.5″ Barrel

The Uberti 1851 Navy London is a .36 calibre percussion revolver.

It reproduces the version of the 1851 Navy manufactured at Colt’s London factory — distinguished by a London-marked barrel rather than a Hartford-proofed one.

It ships to your door. No FFL required — see the ordering section.

What “London” Means on a 1851 Navy

Colt opened a London factory in 1851 to meet British military demand and navigate British proof requirements.

London-manufactured 1851 Navy revolvers carry different barrel markings from Hartford guns — notably the London proof stamps and address marks.

Collectors and reenactors with British military impressions specifically seek the London variant. For most shooters the functional differences are nil; the distinction is in the markings and their historical provenance.

This Version: 7.5″ Barrel, Case Hardened Backstrap

The description mentions two versions of this revolver — 5″ and 7.5″ barrel. This listing is the 7.5″ version.

For the Uberti 1851 Navy London the two differ in more than barrel length:

• 7.5″ version (this one): case hardened backstrap and trigger guard
• 5″ version: brass backstrap and trigger guard

The spec table confirms case hardened frame finish. That’s consistent with the case hardened backstrap noted in the description.

Conversion Cylinder Compatible — Steel Frame

The Uberti 1851 Navy London has a steel frame, which means it accepts Howell Centerfire Conversion Cylinders (sold separately). Those allow the revolver to fire metallic cartridges rather than loose powder and ball.

The Pietta brass-framed revolvers in this range (Spiller & Burr, Traditions 1860 Army) cannot take the conversion. This one can.

The Engraved Cylinder

One detail the features list mentions: the Uberti 1851 Navy London has an engraved, un-fluted cylinder.

On originals, the cylinder scene depicted the Texas Navy’s victory over the Mexican fleet at the Battle of Campeche in 1843.

That engraved scene is part of what makes this pattern visually distinctive compared to the plain cylinders of the Remington pattern.

What You Need to Shoot It

This revolver does not arrive ready to fire.

You need loose black powder or an approved substitute, .375–.380″ round balls, percussion caps sized to these nipples, and lubricant or pre-lubricated wads.

Browse our black powder supplies for consumables.

Never use smokeless powder in any black powder arm. Work within the charge range Uberti specifies.

Cleaning After Every Shoot

Black powder fouling is corrosive. Clean with hot soapy water the same day you shoot.

Remove the cylinder, clean every chamber and nipple, dry thoroughly, then oil before storage. Case hardened components should be oiled promptly — they are durable but not sealed against rust.

Where It Sits in the Range

The Uberti 1851 Navy London is one of three Uberti revolvers in the range and one of four steel-framed options that accept the Howell conversion:

• Pietta 1858 Remington Navy — .36, steel, Remington pattern, conversion-ready
• Uberti 1861 Navy — .36, Uberti quality, round barrel
• Uberti 1849 Wells Fargo — .31, pocket size, no loading lever

For the non-converting options:

• Pietta Spiller and Burr — .36, brass frame, Confederate impression
• Traditions US Marshall — .36, 8″ barrel
• Pietta 1851 Navy .44 and Traditions 1860 Army — .44 calibre options

Frequently Asked Questions

Do I need an FFL to buy this? Generally no. Percussion muzzleloading revolvers aren’t classified as firearms under the Gun Control Act, so federal law usually permits shipment directly to you. State rules vary — check yours.

What makes this “London” rather than standard? The barrel carries London proof marks and address markings rather than Hartford proofs — the distinction from the US-manufactured 1851 Navy. Mechanically the two are the same.

Can I use a Howell conversion cylinder on this? Yes. The steel frame accepts Howell Centerfire Conversion Cylinders, sold separately. Brass-framed revolvers in the range cannot.

Is there a 5″ barrel version available? The description mentions it; we only list the 7.5″ version. Contact us if you need the 5″ configuration.

What does “case coloured” mean on the frame? A mottled blue-grey and brown surface treatment — the same as “case hardened.” The title says “Blue” but the frame finish is case coloured; the barrel is what’s blued.

What ball diameter does it take? .375 to .380 inches — a slightly wider tolerance than most .36 revolvers, accepting either size.

How do I clean it after shooting? Hot soapy water the same day — remove the cylinder and clean every chamber and nipple. Dry completely, then oil. Black powder fouling is corrosive.

Is it suitable for British military reenacting? Yes — specifically for impressions of British forces and personnel who carried Colt London revolvers, a documented historical usage during the 1850s–1860s.
