Historic maritime line-throwing guns occupy a unique niche where naval utility, mechanical simplicity, and collector appeal intersect. For historians, mariners, and serious collectors, original examples that retain period markings and accessories are particularly sought after.

ARMY & NAVY 45-70 LINE THROWER

What makes this example notable

The ARMY & NAVY 45-70 LINE THROWER is a super rare Naval Co. line throwing gun, described as very old and still marked “Roslyn PA USA.” That marking is a key provenance detail — it signals age and likely maritime origin. The listing specifies it comes with two boxes of 45-70 blanks, but it does not include the canister for the line. Priced at $3,000.99, the piece is presented as a rare collectible with room for offers.

Technical and practical considerations

As a Single Shot category item, the ARMY & NAVY 45-70 LINE THROWER is mechanically simple by design. The inclusion of two boxes of 45-70 blanks in the sale is important: line-throwing systems historically used specialized blank cartridges to propel a light line out to a vessel or survivor. Note the listing explicitly states there is no canister for the line — that accessory is central to operational use, so buyers should plan for restoration or sourcing a period-appropriate canister if functional restoration is intended.

Authenticity and condition

Vintage markings like “Roslyn PA USA” add provenance but also raise expectations about condition, original finish, and historical integrity. The seller’s note that the piece is “very old” and “super rare” suggests collectibility; however, assess the bore, mechanical function, and any corrosion before purchase. Given the price point, consider inspection or requesting additional photos on the product page.

Buying notes for collectors

At $3,000.99 the ARMY & NAVY 45-70 LINE THROWER sits in a premium bracket for rare naval single-shot hardware. Expect to factor in restoration, missing accessories (the canister), and safe storage for the included 45-70 blanks. Serious buyers should verify legal transfer requirements and confirm whether blanks are inert or require special handling. If you’re seeking a standout maritime display piece or a restoration project with clear provenance, this item merits close consideration.
