The hunt for museum-quality naval ordnance and commercially rare single-shot pieces brings collectors and tactical historians to unique finds. This firearm blends maritime history with an uncommon surviving purpose-built design that stands out in any serious collection or display.

ARMY & NAVY 45-70 LINE THROWER

Why this ARMY & NAVY 45-70 LINE THROWER matters to collectors

As a SUPER RARE NAVAL CO 45-70 LINE THROWING GUN, this piece is historically specific: marked ROSLYN PA USA and old enough to retain those original stamps. The Army & Navy brand and the “Various” model listing reinforce that this example is a non-standard, hard-to-find variant rather than a mass-produced civilian firearm. Its naval provenance and line-throwing role give it clear museum and display value.

Technical notes and practical considerations

Although the listing lists Caliber as N/A, the included ammunition—two boxes of 45-70 blanks—makes the operating chamber effectively the 45-70 family. The 45-70 cartridge has a long legacy as a heavy, reliable round with significant power and wide availability among collectors and shooters who work with vintage rifles. Here, blanks are what matter for safe demonstration or display of line-throwing function; the unit does not include the canister or line system, so restoration or reproduction of that gear would be required to return it to original operational role.

Condition and restoration potential

The seller emphasizes the age and rarity—“SUPER RARE VERY OLD”—and invites offers. At a listed price of $3,000.99, buyers should weigh historical value against the cost of sourcing an original canister or commissioning a period-appropriate reproduction. For display or non-fired use with blanks, the included ammunition provides immediate provenance and presentation value.
