This is a contract from the 1864-65 period.
Civil War Issue Musket Sling- Baker & McKenney NY Stamped. This firm went into business in 1864 in New York City. Although not date, I believe this was on Baker & McKenney’s early (1864-65) contracts for Infantry accoutrements toward the end of the war. Stamped near the standing loop.
Approximately 49 inches long.
Very good condition show wear, with scuffing, etc. Has a great look for placing on a issued musket that saw service.
