The book ""Civil War Heavy Explosive Ordnance" by Jack Bell contains a very extensive listing of civil war cannon-rifling, categorized by bore-diameter and number of rifling grooves. Unfortunately, in regard to your 7"-caliber Brooke Bolt's sabot with 10-groove rifling marks, the book's only lsiting for a 7-inch cannon with 10 rifling grooves is simply the phrase "CS Rifle." That listing is based on a projectile in Mr. Bell's collection. Apparently, no other evidence exists for a civil war 7-inch caliber cannon with 10-groove rifling. If such a cannon had survived into the 20th-Century, there'd be some documentation of it somewhere.
