Shades of brown vary.  1750's British musket sling is made of 7-8 oz. sanded leather. Approximately 36 inches long, 1-3/16" wide, a solid brass buckle and is non-adjustable. This is the most authentic available. Researched by the Fort Pitt 60th Royal American unit. All of our slings fit all muskets. Your portrayal will dictate your choice of sling.
