Our Assessment: Prior to standardizing the more well-known Trapdoor rifle, the federal government set out to convert existing stores of percussion muskets to cartridge firing rifles. One such conversion is the Roberts patent falling block rifle on offer here. The invention of Brigadier General B.S. Roberts, the original 1861/63 musket breech was replaced with the mechanism seen here—a multi-piece tip-up lever that allowed the wielder to slip one round into the chamber. Finally cocking the hammer locked the breech. Initially endorsed by the New York trial board in 1867, an actual purchase in that state fell through, and Roberts was left to hastily find another buyer. 5,000 would ultimately be purchased for South Carolina’s 13 Coast Guard regiments. Collectors should take notice of this rifle for two reasons: 1.) These rifles were, in effect, experimental, regardless of the number produced, and most simply did not survive consistent use. To have one even in the condition seen here is a boon. 2.) Their experimental nature makes them exceedingly cool. In the case of this rifle, the original 1861/63 musket side plate remains, and so serves as a fascinating example of the old and new existing together, even if for a brief period. A rifle like this is history in the hand. Good luck, and happy bidding!
