This Jacob's Rifle by Swinburn and Son is a double rifle in 52.5 caliber with a 23.5-inch barrel and four-groove rifling, dated to 1860 by its locks. The design came from Brigadier General John Jacob of the Bombay Army. This example still has its sword bayonet, which carries a 30-inch blade and is the scarcer part of the set.

This is an antique rifle for a collector of 19th-century British arms, and the original bayonet is the main draw. The patchbox carries the Jacob's rifle markings. The listing says the metal and wood were refinished neatly, which is common on British guns of the period. Rifles ship to a licensed dealer where the buyer completes the federal paperwork and background check.
